Description

The present invention relates to a pattern molding device and footwear for improving the comfort of footwear.

Shoe making involves many steps and a wide variety of tools, equipment, and materials, so it takes time to learn the techniques and make them, and you won't know how the finished shoes will feel until you actually walk in them. This was what made it difficult. There are some people who are having trouble fitting pre-made shoes, so we thought that providing a way for individuals to make their own shoes to fit their foot size would revitalize the shoe-making market. To this end, we have invented a paper pattern molding machine that allows you to walk in the shoes and check the comfort of the shoes, and footwear manufactured based on the pattern molding machine (see Patent Document 1).

Patent No. 6622371

There are three problems with the pattern molding machine of Patent Document 1 and the footwear manufactured based on it. The first problem is that when the user of footwear indicates the position where the foot hurts, it is necessary to check the condition of the footwear while walking and notify the manufacturer of the footwear on the spot. The problem is that the exact location cannot be confirmed because there are no marks on the footwear. The second problem is that the structure of the upper is made up of a front member and a back member, and when disassembling it to adjust the thickness and position of the cushion, the user instructs the position from the front, and the manufacturer adjusts the cushion from the back. The problem is that the position cannot be determined accurately because the The third problem is that if the central axis of the footwear and the central axis of the foot become misaligned due to walking, it is impossible to quantify and record it on the paper pattern.

In order to solve the above problems, the pattern forming machine of the present invention has a temporary unit sole on which the foot is placed and a temporary upper that presses the top of the foot. The provisional unit sole is provided with a plurality of rows of threading holes, and the provisional upper is provided with a provisional unit sole or provisional upper provided with a plurality of rows of threading holes. A position confirmation mark is attached, and the sewing area is shaped based on the arrangement of the thread holes when the sewing area is basted with the temporary upper placed on the instep of the foot placed on the temporary unit sole. It is equipped with a pattern to be used.

In addition, in the paper pattern molding device of the present invention, the position confirmation marks attached to the temporary upper include the MP joint 1 lateral bone on the inside of the foot, the 5 digit lateral bone of the MP joint on the outside of the foot, and the anterior point of the center of the instep; It may correspond to the positions of at least four parts of the posterior center of the instep.

Further, in the pattern forming machine of the present invention, the position confirmation mark attached to the temporary unit sole may correspond to the positions of at least two parts, a front point of the center of the sole and a rear point of the center of the sole.

Further, in the pattern forming device of the present invention, the position confirmation marks attached to the inside and outside of the leg of the temporary upper may correspond to the position of the threading hole.

In order to solve the above problems, the footwear of the present invention is manufactured using a footwear unit sole and a footwear upper cut out from the above-mentioned paper pattern.

Furthermore, the footwear of the present invention is a footwear in which a unit sole on which the foot is placed and an upper that presses the instep of the foot are sewn together on the inside and outside of the foot, and the unit sole and the upper have thread holes for sewing. They are provided at predetermined intervals, and position confirmation marks are attached to the unit sole or the upper at positions to confirm the positional relationship between the foot and the footwear.

Further, in the footwear of the present invention, the position confirmation mark attached to the upper is the lateral bone of the first digit of the MP joint on the inside of the foot, the lateral bone of the 5th digit of the MP joint on the outside of the foot, the front point of the center of the instep, and the point after the center of the instep. may correspond to the positions of at least four parts.

Further, in the footwear of the present invention, the position confirmation mark attached to the unit sole may correspond to the positions of at least two parts: a front point at the center of the sole and a rear point at the center of the sole.

Further, in the footwear of the present invention, the position confirmation marks attached to the inner and outer sides of the foot of the upper may correspond to the positions of the threading holes.

Further, in the footwear of the present invention, the unit sole includes an insole and an outsole, and a thread is sewn into the edge of the insole that is sewn to the upper, with the thread exposed in the insole. Alternatively, the upper may be sewn to the unit sole by using a separate thread to blind-stitch the exposed thread.

Three problems have been solved by the position confirmation mark of the present invention. The first problem was solved because both the user and the manufacturer were able to accurately grasp the adjustment position. The second problem has been resolved by allowing the manufacturer to clearly determine the position when adjusting the back of the upper. The third problem was solved by being able to quantify the information necessary for pattern correction, which made it possible to record accurate positions on the pattern.

The above-mentioned problem can be solved by aligning the center line of the footwear with the center line of the foot, and manufacturing the footwear by providing marks at each part using this center line as a reference axis, thereby making the positional relationship between the foot and the footwear clear. We thought that if the pattern molding machine and footwear were marked with information about the user's feet, both the user and the manufacturer would be able to visually confirm the marks and share location information correctly. Hereinafter, this mark will be referred to as a "position confirmation mark."

The method of using the position confirmation mark of this invention by marking it on footwear is to select an appropriate method from among several methods depending on the shape of the foot of the user and the manufacturing cost, and to make the footwear comfortable to wear. Provide footwear. Examples thereof will be explained in Examples 1 to 3.

In Example 1, a case will be described in which a paper pattern molding machine is manufactured exclusively for an individual's foot. This method is suitable for cases where existing shoes do not suit an individual's feet and the overall balance between the foot and footwear needs to be reconsidered. In the description of the present invention, all operations for obtaining foot information will be referred to as measuring. Furthermore, the first toe side of the foot and footwear is referred to as the inside, and the fifth toe side is referred to as the outside.

The purpose of the present invention is to prevent or improve shoe chafing and improve the comfort of wearing shoes. To do this, it is necessary to clarify each case in which shoe blisters occur. Shoe blisters occur when the foot and footwear are subjected to friction and weight during walking. The cases that we are currently aware of are as follows.
(1) When the heel touches the ground, the corner of the heel hits the ground.
(2) When supinating, the outside of the shoe's opening rubs.
(3) When pronating, the inside of the shoe opening rubs.
(4) When the heel floats, the opening of the shoe rubs against the cuneiform bone.
(5) When the heel floats, the inside and outside of the shoe opening rub. Especially the outside is scratched.
(6) When the footwear is bent, the wrinkles of the upper are pressed against the foot.
(7) When weight is applied to the MP joint, the horizontal arch of the sole of the foot expands and the sides of the ball of the foot and the ball of the little foot contact the footwear.
(8) The end surface of the upper front opening rubs against the cuticle of the finger.
(9) During the kicking motion, the fingertips hit the step on the outer periphery of the footwear.

Furthermore, one of the reasons why shoes become uncomfortable is that the shape of the unit sole does not match the shape of your foot. The shape of the unit sole and the foot will be explained with reference to FIGS. 29 and 30. FIG. 29 is a view of the foot seen from the sole, and is a view showing the "dogleg" (curvature) of the foot. FIG. 30 is a top view of the foot in the footwear, showing that the heel of the foot is protruding from the footwear. The distance of protrusion can be known from the position confirmation mark 30B marked on the upper surface of the unit sole.

As a typical feature of a foot, as shown in FIG. 29, a front center line 29B and a rear center line 29C intersect at a dogleg angle 29A, forming an angle. This angle varies from person to person, and if there is a difference between the shape of the unit sole and the shape of the sole of an individual's foot, a problem occurs in which the heel of the foot protrudes from the footwear, as shown in FIG. 30. This problem can be solved by ensuring that the footwear centerline 30A, which is the centerline of the footwear, and the foot centerline AT1, which is the centerline of the foot, do not differ greatly.

By using a unit sole that matches the individual's dogleg shape, the contact between the upper and the foot is even, creating a feeling that wraps around the entire foot. However, simply using a unit sole tailored to an individual's dogleg shape may not be enough to resolve the heel misalignment. This is because heel misalignment occurs due to various factors such as the stride length during walking, the weight applied during supination and pronation, and the walking time.

This section shows what to do if the heel slips despite using a unit sole that matches the dogleg shape. The top surface of the unit sole will dent in the weight-bearing area after several months of wear. In addition, the areas where the soles of the feet come into contact become dirty and leave evidence of walking. By looking at the difference between the dent on the upper surface of the unit sole, the evidence of walking, and the position confirmation mark 30B, the distance of protrusion can be determined. Based on this information, the pattern is corrected and the footwear is remade. There are also cases where footwear and feet shift forward or backward when walking. Even in such a case, the position confirmation mark can be used as a landmark to know the distance of deviation and correct the paper pattern.

As mentioned above, shoe blisters are caused by multiple factors, so it may be difficult to provide comfortable footwear simply by measuring the foot in a static state. Recognize. In order to make footwear that is comfortable to wear, it is time-consuming but highly reliable to check how the person walks and make improvements if there are any problems. By placing position confirmation marks on the pattern molding machine and footwear, the positional relationship between the pattern molding machine and footwear and the foot becomes clear, allowing for accurate improvement.

The paper pattern forming machine of the present invention marks a position confirmation mark according to the shape of the individual's foot. The shape of an individual's foot includes the outer circumference of the foot, the center line of the foot, the position of the bones, the position of the nails, and the unevenness of the foot, and in order to obtain this information, it is necessary to measure the foot.

The measuring method will be explained with reference to FIGS. 1 to 7. First, as shown in FIG. 1, place the foot on the top surface of paper 1A, trace the outer circumference of the foot with a pencil, and draw a line 1B of the outer circumference of the foot. The paper on which this was recorded is shown in FIG. The method for measuring the parts of the foot will be explained below, and FIG. 7 shows the recording of the measurement information. Next, there is a region called the base of the fifth metatarsal S5, located along the outer side of the instep from the base of the ankle (Figure 2). There is a concave bone in this area, and you can tell its location by feeling it. Mark this position. This measuring point is called the base measuring point SS5 (FIG. 7). Next, at the center of the top of the foot and below the ankle, there is a part called the cuneiform bone S4 (Figure 3). The bone in this area has a convex shape, so you can tell its location by feeling it. Starting from the cuneiform S4, mark the outside of the cuneiform S4A, which is the position taken along the outside of the carapace. This measuring point is referred to as cuneiform bone measuring point SS4 (FIG. 7). Next, a mark is placed at the position of the first toe center S12 (FIG. 4). This measuring point is referred to as the first toe center measuring point SS12 (FIG. 7). Next, mark the position of the first toe nail portion S1 (FIG. 4). This measuring point is referred to as the first toe nail measuring point SS1 (FIG. 7). Next, there is a part called MP joint 1 digit lateral bone S2 on the side of the thenar ball (Figure 4). The bone in this area has a convex shape, so you can tell its location by feeling it. Mark this position. This measuring point is referred to as MP1 toe measuring point SS2 (FIG. 7). Next, on the side of the little foot ball, there is a part called MP joint 5 lateral bone S3 (Figure 4). The bone in this area has a convex shape, so you can tell its location by feeling it. Mark this position. This measurement point is referred to as MP5 toe measurement point SS3 (FIG. 7). Next, a pencil is inserted and marked at the position of the first toe and the second toe S13 (FIG. 5). This measuring point is referred to as the first toe to second toe measuring point SS13 (FIG. 7). Next, insert a pencil and mark the position of the second toe and third toe S14 (FIG. 5). This measuring point is referred to as the second to third toe measuring point SS14 (FIG. 7). Next, mark the position of the bottom center rear S10 (FIG. 6). This measuring point is referred to as the bottom center measuring point SS10 (FIG. 7). Next, consider the heel to be a circle and mark the inner apex of the heel, S9 (FIG. 6). This measuring point is referred to as the inner heel measuring point SS9 (FIG. 7). Next, the heel is likened to a circle and a mark is placed on the outside vertex of the heel, S8 (FIG. 6). This measuring point is referred to as outside heel measuring point SS8 (FIG. 7).

Next, a method of drawing a temporary unit sole pattern for the pattern forming machine will be explained with reference to FIGS. 7 to 10. Drawings are performed in the order of FIGS. 8 to 10 based on FIG. 7. In the description, the width direction of the foot is referred to as the horizontal direction, and the length direction of the foot is referred to as the vertical direction. FIG. 8 shows lines drawn in the vertical and horizontal directions based on the measurement points in FIG. 7. The reason for drawing lines in the vertical and horizontal directions is shown below. If there is a misalignment in the positional relationship between the temporary unit sole of the pattern molding machine and the temporary upper, the pattern molding machine and the footwear produced using it will be twisted, causing the wrinkles of each upper to enter diagonally and hit the foot. Occur. A temporary unit sole and a temporary upper are manufactured using these vertical and horizontal lines as reference lines, and by combining them, it is possible to eliminate misalignment of each member.

A method of drawing the foot center line AT1, which is a vertical reference line, will be explained with reference to FIG. Connect the second toe midpoint 8A, which is the midpoint between the first toe measurement point SS13, the second toe measurement point SS14, and the bottom center measurement point SS10, and draw a line that passes through the outer circumference of the foot. If you pull it, you can draw the foot center line AT1.

Next, how to draw horizontal lines YS1 to YS5, which are horizontal reference lines, will be explained. Perpendicularly to the foot center line AT1, using the measurement points of Fig. 7 as the 1st toe nail measurement point SS1, MP1 toe measurement point SS2, MP5 toe measurement point SS3, cuneiform bone measurement point SS4, and base measurement point SS5. Draw a line so that The reference lines for the above five measuring points are horizontal line YS1, horizontal line YS2, horizontal line YS3, horizontal line YS4, and horizontal line YS5 in FIG. 8, respectively. Also, by drawing a reference line, the following four intervals can be created. Distance KK1 between horizontal line YS1 and horizontal line YS2. Distance KK2 between horizontal line YS2 and horizontal line YS3. Distance KK3 between horizontal line YS3 and horizontal line YS4. Distance KK4 between horizontal line YS4 and horizontal line YS5.

Next, a method for drawing FIG. 9 will be explained based on FIG. 8. First, a method of drawing the unit sole outer circumferential line 9C (FIG. 9) will be explained. The unit sole outer circumference line 9C is drawn so as to surround the outer circumference of the foot while ensuring the width of the seam allowance 9F. At this time, the toe margin 9D and heel margin 9E are designed so that they do not hinder walking and do not spoil the appearance.

Next, how to draw the suture hole reference line 9H will be explained. Draw a line parallel to the unit sole outer circumferential line 9C and ensuring the width of the seam allowance 9F. By doing this, intersections between the horizontal lines YS1 to YS5 and the suture hole reference line 9H are created. These intersection points become reference points KT1 to KT5. Next, a method of drawing the suture hole position 9G will be explained. Measure the length of each of the adjacent reference points KT1 to KT5. Divide the measured value by an integer value to obtain an integer value of 6.5 to 8 mm. By doing this, the pitch can be determined within the range of 6.5 to 8 mm. This pitch calculation is performed between adjacent reference points KT1 to KT5. Points are provided on the suture hole reference line 9H according to the pitch. A horizontal line is drawn at the pitch point thus determined, and the intersection with the suture hole reference line 9H becomes the suture hole position 9G. Do this on both the inside and outside of your foot. At this time, the number of suture hole positions 9G on the outside and inside of the foot in each block with intervals KK1 to KK4 is kept the same. In this way, suture hole positions other than the reference points can be plotted without changing the positions of the reference points KT1 to KT5. Next, since it is necessary to provide suture holes according to the size of the temporary upper, several suture hole positions 9G are provided on the toe side from the horizontal line YS1 and several on the heel side from the horizontal line YS5. The reason why the pitch was set in the range of 6.5 to 8 mm is that if the distance between the holes is narrower than 6.5 mm, there is a risk that the upper will tear when the thread is sewn in. This is because if it is wider than millimeters, the thread will not be tight enough and the temporary upper seams will float. However, this value may change depending on the size of the hole, the thickness of the thread, and the thickness of the upper material if conditions change.

Next, the measuring points shown in FIG. 7, which are the outer heel measuring point SS8, the inner heel measuring point SS9, the bottom center measuring point SS10, and the first toe center measuring point SS12, are marked on the drawing of FIG. 9. These become the outside heel confirmation mark SA8, the inside heel confirmation mark SA9, the bottom center confirmation mark SA10, and the first toe center confirmation mark SA12. The front sole center confirmation mark SA11 is placed on the foot center line AT1 and at the tip of the foot. In this way, the drawing in FIG. 9 is completed.

Next, a method for drawing FIG. 10 will be explained based on FIG. 9. First, a parallel external line 10D and a parallel internal line 10E are drawn so that they are parallel to the suture hole reference line 9H in FIG. The width of this parallel line is determined based on experience. Next, a suture hole perpendicular line 10C is drawn at all suture hole positions 9G so as to pass through the point of the suture hole position 9G and be orthogonal to the parallel external line 10D and the parallel internal line 10E. At this time, the suture hole perpendicular line 10C is drawn at an angle perpendicular to the foot center line AT1. Do this on the outside and inside of your foot. This will create three rows of suture holes. Accordingly, in order to secure the seam allowance 9F for the inside and outside of the foot, the seam allowance is designed to have a seam allowance step 10B. In this way, a temporary unit sole outer circumferential line 10A can be drawn.
Next, the position confirmation marks (5 pieces) shown in FIG. 9 are shown in FIG. Mark. In this way, the drawing in FIG. 10 is completed. Next, by cutting out the pattern margin 11A from the pattern shown in FIG. 10 as shown in FIG. 11, a temporary unit sole pattern for the pattern molding machine is completed.

Next, a method of drawing a temporary upper pattern will be explained with reference to FIGS. 12 to 15. For the temporary upper pattern, measure the instep of the user's foot and draw the pattern based on the measurements. A method for measuring the top of the foot will be explained with reference to FIG. 12.
First, prepare a piece of tape such as tape 12A, which is cut by drawing a straight line on it, and attach it to the center of the instep of the foot so as to overlap the cuneiform bone. Next, place your foot on the paper shown in Figure 8. At this time, the measurement points are 1st toe nail measurement point SS1, MP1 toe measurement point SS2, MP5 toe measurement point SS3, cuneiform bone measurement point SS4, and base measurement point. Place the foot part on the SS5 mark. Next, the distance from the intersection of the outer circumferential line 1B of the foot and the horizontal lines YS2, YS3, and YS4 to the center line of the instep of the foot is measured using a tape measure 12B. The values obtained from the measurements were recorded on the paper shown in Figure 8, and the result is shown in Figure 13. The measurements were taken at six locations: outer horizontal length GN2, GN3, and GN4, and inner horizontal length UN2, UN3, and UN4.

Next, a method for drawing FIG. 14 will be explained based on FIG. 13. We measured the top of the foot in 6 places, but if we were to make an upper with the same length as these measurements, it would be uncomfortable and loose. Other factors such as the thickness of the material and the unevenness of the wrinkles on the upper also affect comfort. To prevent this from happening, multiply the numbers measured at six locations on your feet by a multiplication factor.
It is necessary to adjust the size of the upper part by part. This multiplication rate is determined based on empirical rules for each of the six locations.

Next, the positions of the upper reference points AKT2 to AKT4 are determined on the horizontal lines YS2 to YS4 in FIG. 14 by multiplying the outer horizontal lengths GN2, GN3, and GN4 in FIG. 13 and the inner horizontal lengths UN2, UN3, and UN4 in FIG. 13 by the multiplication factor. Upper reference points AKT2 to AKT4 are determined on the outside and inside of the foot. The drawing in FIG. 14 will be proceeded based on the upper reference points AKT2 to AKT4, the intervals KK1 to KK4, and the foot center line AT1. Note that the positions of the upper reference points AKT1 and AKT5 are determined by empirical rules.

Next, draw the suture hole reference line 9H so that it is longer than the horizontal lines YS1 and YS5 while smoothly connecting the upper reference points AKT2 to AKT4. Next, a method of drawing the suture hole position 9G will be explained. The lengths of adjacent upper reference points of upper reference points AKT1 to AKT5 are measured. Divide the length of each adjacent upper reference point by the integer value when calculating the pitch of the suture hole position 9G in FIG. 9 to find the length of the pitch. By doing so, the number of suture hole positions 9G in FIG. 9 and the suture hole positions 9G in FIG. 14 can be made the same. A horizontal line is drawn at the pitch point thus determined, and the intersection with the suture hole reference line 9H becomes the suture hole position 9G. Next, I will explain how to draw the outer periphery of the upper pattern. By setting the width of the seam allowance 9F on the suture hole reference line 9H and drawing parallel lines, the outer and inner circumferential lines of the foot can be drawn. Next, lines for the toe lateral line 14D and ankle lateral line 14E are drawn in a well-balanced manner according to a rule of thumb. This completes the outer circumference of the upper.

Next, the upper front and back suture holes 14C will be explained. The upper has a structure in which two layers, a front member and a back member, are stacked one on top of the other, and a cushioning material is placed in between to adjust the comfort of the wearer.Since the front member and back member are sewn together with thread, it is necessary to provide a hole for sewing. This suturing hole is the upper front and back suture hole 14C. The drawing method is to draw a line parallel to the toe lateral line 14D and the ankle lateral line 14E to determine the position of the suture hole. It can be used as a landmark as the center position (Figs. 18 and 19). Determine the position of the central suture, and use empirical rules to determine the pitch of the remaining suture holes.

Next, as shown below, position confirmation marks (12 pieces) are marked in FIG. 14 based on the measurement points in FIG. 7. At this time, the measurement points in FIG. 7, such as 1st toe nail measurement point SS1, MP1 toe measurement point SS2, MP5 toe measurement point SS3, cuneiform bone measurement point SS4, and base measurement point SS5, are on the horizontal lines YS1 to YS5 in FIG. It is on the line and marked on the inside and outside of the foot. The position confirmation mark marked on the outside of the upper in FIG. 14 is shown below. External first toe nail confirmation mark SG1, external MP1 toe confirmation mark SG2, external MP5 toe confirmation mark SG3, external cuneiform bone confirmation mark SG4, external base confirmation mark SG5. The position confirmation mark marked on the inside of the upper in FIG. 14 is shown below. Inner 1st toe nail confirmation mark SU1, inner MP1 toe confirmation mark SU2, inner MP5 toe confirmation mark SU3, internal cuneiform bone confirmation mark SU4, inner base confirmation mark SU5. Furthermore, an instep center front confirmation mark ST6 and an instep center back confirmation mark ST7 are marked on the foot center line AT1. At this time, if the vertical position of the instep center front confirmation mark ST6 is close to the toe lateral line 14D, it will be easier to confirm whether it is aligned with the center of the foot. For the same reason, the instep center rear confirmation mark ST7 should be near the ankle lateral line 14E. This completes Figure 14. Note that by changing the lengths of the intervals KK1 to KK4 between the uppers, it is possible to adjust the size of the unevenness of wrinkles that occur on the upper.

Up to this point, the drawing method of FIG. 14 has been explained. Since the suture holes are in one row in this FIG. 14, the suture holes are made in three rows as shown in FIG. 15 by facing the pattern forming device. First, a parallel external line 10D and a parallel internal line 10E are drawn parallel to the suture hole reference line 9H in FIG. 14. The width of this parallel line is determined based on experience. Next, a suture hole perpendicular line 10C is drawn at all suture hole positions 9G so as to pass through the point of the suture hole position 9G and be orthogonal to the parallel external line 10D and the parallel internal line 10E. At this time, the suture hole perpendicular line 10C is drawn at an angle perpendicular to the foot center line AT1. Do this on the outside and inside of your foot. This will create three rows of suture holes. Next, adjust the width of the seam allowance to ensure a seam allowance of 9F for the inside and outside of the foot. Next, the position confirmation marks (12 pieces) shown in FIG. 14 are: external first toe nail confirmation mark SG1, external MP1 toe confirmation mark SG2, external MP5 toe confirmation mark SG3, external cuneiform bone confirmation mark SG4, external base confirmation mark SG5, Inner 1 toe nail confirmation mark SU1, inner MP1 toe confirmation mark SU2, inner MP5 toe confirmation mark SU3, inner cuneiform bone confirmation mark SU4, inner base confirmation mark SU5, instep center front confirmation mark ST6, instep center back confirmation mark ST7. Mark in Figure 15. In this way, the temporary upper pattern for the pattern molding machine is completed. Although the upper has a structure in which a front member and a back member are overlapped, the pattern drawing procedure for the front member and back member is the same.

Next, the structure and manufacturing method of the paper pattern molding device will be explained with reference to FIGS. 16 to 19. As shown in FIG. 16, the temporary upper 16A is made up of two members, a front member 16B and a back member 16C, and the upper front and back suture holes 14C provided on the end faces of the members are sutured with a needle and thread 16D. The assembly is completed.

Next, the structure of the paper pattern forming machine will be explained with reference to FIG. The pattern molding machine consists of two members: a temporary upper 16A and a temporary unit sole 17A. The temporary unit sole 17A consists of an inner sole 17B and an outsole 17C. The temporary upper 16A and the midsole 17B have threading holes for basting in each stitching area on the inside and outside of the foot, such as the temporary upper threading hole 17F and the temporary unit sole midsole threading hole 17E. A plurality of rows (three rows) are provided for each. These holes are provided based on the temporary unit sole pattern shown in FIG. 10 and the temporary upper pattern shown in FIG. 15. The midsole 17B and the outsole 17C are bonded together only at the adhesive portion 17D shown by diagonal lines. With this structure, the temporary upper threading hole 17F and the temporary unit sole insole threading hole 17E can be sewn together using the needle and thread 16D, and the user can walk by putting his/her feet therein. The pattern molding machine completed in this way is shown in FIGS. 18 and 19. FIG. 18 is an external view of the foot viewed from the outside, and FIG. 19 is an external view of the foot viewed from the inside.

As shown in FIGS. 18 and 19, a position confirmation mark is marked on the paper pattern forming machine, and when the foot is inserted, the position of the foot part and the position confirmation mark are in the same position. The position confirmation mark of the pattern forming machine was made based on the temporary unit sole pattern shown in FIG. 10 and the temporary upper pattern shown in FIG. 15. The position confirmation marks (12) marked on the temporary upper are shown below. External 1st toe nail confirmation mark SGK1, External MP1 toe confirmation mark SGK2, External MP5 toe confirmation mark SGK3, External cuneiform bone confirmation mark SGK4, External base confirmation mark SGK5, Inner 1st toe nail confirmation mark SUK1, Inner MP1 toe confirmation mark SUK2 , internal MP5 toe confirmation mark SUK3, internal cuneiform bone confirmation mark SUK4, internal basal part confirmation mark SUK5, instep center front confirmation mark STK6, instep center back confirmation mark STK7. The position confirmation marks (5 pieces) marked on the temporary unit sole are shown below. Outside heel confirmation mark SAK8, inside heel confirmation mark SAK9, bottom center back confirmation mark SAK10, bottom center front confirmation mark SAK11, 1st toe center confirmation mark SAK12.

Next, how to use the paper pattern forming device will be explained with reference to FIGS. 18 and 19. First, a temporary upper 16A and a temporary unit sole 17A are formed by sewing together multiple rows of holes at the position of the stitching hole reference line among the three rows of holes. This suture hole reference line is a reference line drawn to match the foot after measuring the foot. Put your foot in there and find out if there are any problems with the temporary upper 16A, such as lifting or tightness, and if there is a problem, untie the thread and resew it. After that, if you walk on the shoes and find that the shoes are not comfortable, untie the threads, re-stitch them, and repeat this process until the shoes are comfortable. At this time, the comfort can be adjusted smoothly by using the position confirmation mark marked on the pattern molding machine. In this way, the positions of the outer foot fitting hole 18A and the inner foot fitting hole 19A, which are sewing holes suitable for the individual's foot size, can be obtained.

Next, a method of drawing the footwear upper pattern 21A (FIG. 21) based on the information of the outer foot fitting hole 18A and the inner foot fitting hole 19A will be explained with reference to FIGS. 18 to 21. Figures 18 and 19 show that the stitches were sewn to match the foot, and the holes used for the stitching were the outer foot fitting hole 18A and the inner foot fitting hole 19A. The hole positions of the outer foot fitting hole 18A and the inner foot fitting hole 19A are
When copied onto the pattern shown in FIG. 15, it will look like the black circle outer foot fitting hole 20B and the black circle inner foot fitting hole 20C of the temporary upper pattern 20A (FIG. 20). By doing this, you can find the hole positions on the pattern paper that suit your individual feet.
Next, a method for drawing the footwear upper pattern 21A shown in FIG. 21 based on the temporary upper pattern 20A shown in FIG. 20 will be described.
After omitting the holes other than the black circle outer leg matching hole 20B and the black circle inner leg matching hole 20C of the temporary upper pattern 20A, make the holes parallel to the black circle outer leg matching hole 20B and the black circle inner leg matching hole 20C, like the upper seam allowance 21B. Provide a seam allowance. By doing this, the footwear upper pattern 21A can be drawn. Note that the uppers shown in Figures 18 and 19 are manufactured based on Figure 15, and Figures 20 and 21 are drawn based on Figures 15, 18, and 19, so these position confirmation marks are placed in the same position and have the same name. are marked. The position confirmation marks (12 pieces) marked on the upper in FIGS. 20 and 21 are shown below. External 1st toe nail confirmation mark SGK1, External MP1 toe confirmation mark SGK2, External MP5 toe confirmation mark SGK3, External cuneiform bone confirmation mark SGK4, External base confirmation mark SGK5, Inner 1st toe nail confirmation mark SUK1, Inner MP1 toe confirmation mark SUK2 , internal MP5 toe confirmation mark SUK3, internal cuneiform bone confirmation mark SUK4, internal basal part confirmation mark SUK5, instep center front confirmation mark STK6, instep center back confirmation mark STK7.

The drawing method for the temporary unit sole insole pattern 22A in FIG. 22 and the footwear unit sole insole pattern 23A in FIG. 23 is the same as the drawing method for the temporary upper pattern 20A and the footwear upper pattern 21A. Note that the unit soles shown in Figures 18 and 19 are manufactured based on Figure 10, and Figures 22 and 23 are drawn based on Figures 10, 18, and 19, so these position confirmation marks are in the same position. The name will be marked. The position confirmation marks (5 pieces) marked on the unit sole in FIGS. 22 and 23 are shown below. Outside heel confirmation mark SAK8, inside heel confirmation mark SAK9, bottom center back confirmation mark SAK10, bottom center front confirmation mark SAK11, 1st toe center confirmation mark SAK12. Using the thus drawn footwear upper pattern 21A (FIG. 21) and the footwear unit sole insole pattern 23A (FIG. 23), sandals as shown in FIG. 25 can be manufactured. Note that the footwear unit sole insole pattern 23A can be used as a cutting pattern for both the insole 17B and outsole 17C shown in FIG. 24.

Next, referring to FIGS. 21, 23, and 24, using the footwear upper pattern 21A (FIG. 21) and the footwear unit sole insole pattern 23A (FIG. 23), create the footwear upper 24A (FIG. 24) and the footwear unit sole 24B ( The processing method of FIG. 24) will be explained. When the footwear upper pattern 21A, which is a cardboard, is placed on top of the material used for the footwear upper 24A, such as leather, synthetic leather, or cloth, and cut along the outer shape, and a threading hole is provided by drilling, the footwear upper 24A is made. Can be manufactured. Note that the footwear upper 24A has a structure in which a front member and a back member are overlapped and sewn together, similar to the temporary upper 16A shown in FIG. In addition, the processing method for the insole 17B (Fig. 24) is to place the footwear unit sole insole pattern 23A, which is cardboard, on top of a material such as leather or synthetic leather, cut it along the outer shape, and punch holes for threading. By providing this, the inner sole 17B can be manufactured. The outsole 17C (FIG. 24) can be manufactured by placing the footwear unit sole insole pattern 23A on a material such as leather or synthetic resin and cutting it along the outer shape.

Next, with reference to FIG. 24, the structure and sewing method of the footwear upper 24A and the footwear unit sole 24B will be explained. The structure of the footwear upper 24A is such that upper stitching holes 24C are formed on both sides for stitching with the footwear unit sole 24B. The structure of the footwear unit sole 24B is such that a thread is sewn into the edge of the midsole 17B, which is sewn to the footwear upper 24A, in an exposed state like an exposed thread 24D. After the outsole 17C is sewn in, the outsole 17C is attached. Next, the method of sewing the footwear upper 24A and the footwear unit sole 24B is to sew the exposed threads 24D of the footwear unit sole 24B to the holes on both sides of the footwear upper 24A. By scooping up the exposed thread 24D with the thread 16D and sewing it, sandals as shown in FIG. 25 are completed. By blind stitching the exposed thread 24D in this manner, the footwear upper 24A and the footwear unit sole 24B can be sewn together without spoiling the appearance. FIG. 25 is a view of the footwear manufactured in this manner as seen from the outside of the foot, and FIG. 26 is a view of the footwear as seen from the inside of the foot.

The footwear shown in FIGS. 25 and 26 is marked with position confirmation marks shown in the paper patterns of FIGS. 21 and 23, which are the same as those made with a pattern molder. The position confirmation marks (12) marked on the upper of the footwear are shown below. External 1st toe nail confirmation mark SGH1, External MP1 toe confirmation mark SGH2, External MP5 toe confirmation mark SGH3, External cuneiform bone confirmation mark SGH4, External base confirmation mark SGH5, Inner 1st toe nail confirmation mark SUH1, Inner MP1 toe confirmation mark SUH2 , internal MP5 toe confirmation mark SUH3, internal cuneiform bone confirmation mark SUH4, medial basal part confirmation mark SUH5, instep center anterior confirmation mark STH6, instep center posterior confirmation mark STH7. The position confirmation marks (5 pieces) marked on the inner sole of footwear are shown below. Outside heel confirmation mark SAH8, inside heel confirmation mark SAH9, bottom center back confirmation mark SAH10, bottom center front confirmation mark SAH11, 1st toe center confirmation mark SAH12.

Next, a method of adjusting the sandals shown in FIG. 25 (FIG. 26) to the foot circumference of the user will be explained. First, a user tries walking wearing the sandals shown in FIG. 25. At that time, if the foot circumference of the sandals is large, the sandals will float and may fall off. If it is about to come off, cut the sutures in the upper front and back suture holes 14C, separate the front and back members, and insert the cushioning material 27A to adjust as shown in FIG. Check the walking again, and if there is a problem, repeat the adjustment by changing the thickness, position, material, shape, etc. of the cushioning material 27A. If there is no problem with comfort, the upper front and back suture holes 14C are sutured. Note that the adjustment of the cushioning material can also be performed by cutting the suture at the blind stitched portion 24E and separating the footwear upper 24A and the footwear unit sole 24B, as shown in FIG.

Next, an adjustment method when the foot circumference of the footwear is tight will be explained with reference to FIG. 28. If the shoe is uncomfortable to wear, it is necessary to increase the foot circumference of the footwear upper 24A. The footwear upper 24A (FIG. 28) and the footwear unit sole 24B (FIG. 28) are separated by cutting and untying the suture of the blind stitched portion 24E shown in FIG. 24. Then, the foot circumference increasing member 28A is sandwiched between the footwear upper 24A and the footwear unit sole 24B. The foot circumference increasing member 28A is made of leather or a similar material, has a shape that follows both sides of the footwear unit sole 24B, and has holes for hand sewing in the same manner as on both sides of the upper. By sandwiching the foot circumference increasing member 28A between the footwear upper 24A and the footwear unit sole 24B and sewing them together with blind stitches, the foot circumference of the footwear upper 24A can be increased and the tight wearing comfort can be improved.

Next, the use of position confirmation marks will be explained. When I asked the user how comfortable they were after wearing the pattern molding machine and footwear, the user replied, ``I can walk in them, so this is fine,'' but after a few days, the user said, ``I'm getting blisters, so I'd like you to adjust the shoes.'' ” There is a request. In order to prevent shoe chafing, users must first learn about the position of the bones in their feet, walking motion, the position of excessive weight, and the position of friction, as ``prior knowledge about shoe chafing,'' and check their walking to ensure the comfort of their shoes. You need to be able to make decisions. At this time, if the pattern molding machine and the footwear are marked with position confirmation marks, the pedestrian can be more careful and confirm his/her walking.

Furthermore, the use of position confirmation marks will be explained. We measure the feet, make a pattern molder and make the footwear, and when we hand it over to the user, we ask them to put their feet in and check that the footwear fits. I don't know the position or whether it matches the center line of the foot. By marking the position confirmation marks on the pattern molding machine and the footwear, both the manufacturer and the user can confirm that the product has been manufactured according to the measurements by looking at the position confirmation marks on the foot part and footwear. .

Furthermore, the use of position confirmation marks will be explained. There are production, sales, and adjustment processes in providing pattern molding equipment and footwear services. If different people are in charge of each process, even if the manufacturer understands "prior knowledge about shoe blisters," it may not be communicated to the seller or adjuster. If prior knowledge about shoe blisters is shared among the people in charge of each process, prevention and improvement of shoe blisters can be carried out smoothly. In such cases, the location can be clarified by marking the location confirmation mark.

Furthermore, the use of position confirmation marks will be explained. The user instructs the adjuster about the adjustment position for comfort, but the instructions are given from the pattern molding machine and the front side of the footwear. When the adjuster separates the footwear and performs adjustment work from the back side, the adjustment position can be determined by using the position confirmation mark as a landmark. Note that the work will be easier if a position confirmation mark is marked on the side of the upper where the front and back members meet.

Furthermore, the use of position confirmation marks will be explained. After wearing footwear for several months, the insole area where the foot rests becomes dented and dirty. By looking at the position confirmation mark on the insole, dents, and dirt, you can tell whether the footwear matches your foot. In particular, numerical information can be obtained for forward slippage of the foot and lateral slippage of the heel by measuring the distance between the position confirmation mark, dent, and dirt. This numerical information can be used to make footwear.

Furthermore, the use of position confirmation marks will be explained. After wearing footwear for several months, the upper will stretch and wrinkle. Numerical information can be obtained by measuring the deviation between the position confirmation mark marked on the upper and the part of the foot. This numerical information can be used to make footwear.

Furthermore, the use of position confirmation marks will be explained. If you wear the footwear for a few months and separate the upper and unit sole and place them on a pattern, you can see how much the shoe has deformed. By knowing this deformed value, it is possible to manufacture footwear assuming the deformation.

In addition, the pattern molding device and footwear of the present invention have suture holes with the foot part as a reference point, so by counting the suture holes and seams from the end, it is possible to know the foot parts and bone positions. can. This allows the suture holes and stitches to function as scales.

Although this invention has been explained using sandals, it can also be applied to footwear of different designs, such as boots, short shoes, and pumps. Note that the upper can also be adjusted by attaching a cushioning material to the back surface of the front member without using the back member.

Note that there are several methods for marking the position confirmation mark, such as making a hole with a hole punch or marking a dot with a punch. Note that it is preferable that the position confirmation mark be placed in a position that is visible and does not spoil the design. Note that the position confirmation mark can also be placed on the outer periphery of the suture hole in the upper. It is also possible to incorporate location confirmation marks into the design.

The shape of the foot is unique to each individual due to factors such as bunions, genetics, and deformities caused by sports. You can set a new part of the foot according to its characteristics and use this part as a reference point to draw the paper pattern. At this time, a position confirmation mark is marked on the newly set part of the foot.

Note that the pattern forming device may have multiple rows of suture holes other than three rows.

In addition, if you draw a reference line on the back of the upper, the accuracy of adjustment will be greatly improved.

In addition, if placing position confirmation marks in all positions would spoil the external design, it is sufficient that the marks are placed at the minimum number of positions shown below. On the temporary upper of the pattern molder (Figures 18 and 19), there are the inner MP1 toe confirmation mark SUK2 on the inside of the foot, the outer MP5 toe confirmation mark SGK3 on the outside of the foot, the instep center front confirmation mark STK6, and the instep center back confirmation mark. Mark at least 4 marks STK7. At least two marks are made on the temporary unit sole: a bottom center front confirmation mark SAK11 and a bottom center back confirmation mark SAK10. The upper of the footwear (Figures 25 and 26) has at least the following: the inner MP1 toe confirmation mark SUH2 on the inside of the foot, the outer MP5 toe confirmation mark SGH3 on the outside of the foot, the instep center front confirmation mark STH6, and the instep center rear confirmation mark STH7. Mark 4.
At least two marks are made on the unit sole of the footwear: a sole center front confirmation mark SAH11 and a bottom center rear confirmation mark SAH10. Furthermore, the accuracy will be improved if position confirmation marks are marked at the following positions. Three marks are made on the temporary upper of the pattern molder (FIGS. 18 and 19): inner first toe nail confirmation mark SUK1, outer cuneiform bone confirmation mark SGK4, and outer base confirmation mark SGK5. Three marks are made on the temporary unit sole of the pattern molding machine: an outside heel confirmation mark SAK8, an inside heel confirmation mark SAK9, and a first toe center confirmation mark SAK12. Three marks are placed on the upper of the footwear (FIGS. 25 and 26): an inner first toe nail confirmation mark SUH1, an outer cuneiform bone confirmation mark SGH4, and an outer base confirmation mark SGH5. Three marks are placed on the unit sole of the footwear: an outside heel confirmation mark SAH8, an inside heel confirmation mark SAH9, and a first toe center confirmation mark SAH12.

The above-mentioned minimum number of position confirmation marks to be marked will be explained. Minimally mark the temporary upper of the pattern molder,
The internal MP1 toe confirmation mark SUK2 on the inside of the foot and the external MP5 toe confirmation mark SGK3 on the outside of the foot refer to the positions of the medial and lateral bones on the side of the MP joint. Since the walking movement is based on the MP joint, whether the MP joint of the foot matches the part corresponding to the MP joint on the pattern molding machine has a great effect on the comfort of the foot. For these reasons, position confirmation marks such as the inner MP1 toe confirmation mark SUK2 and the outer MP5 toe confirmation mark SGK3 are required.

Furthermore, the instep center front confirmation mark STK6 and the instep center back confirmation mark STK7, which are minimally marked on the temporary upper of the pattern molding machine, refer to the longitudinal center of the instep. The pattern molder creates a temporary upper that aligns with the center line of the foot, and whether the center line of the foot and the center line of the pattern molder match greatly affects the comfort of the shoe. For these reasons, position confirmation marks such as the instep center front confirmation mark STK6 and the instep center rear confirmation mark STK7 are required.

Furthermore, the bottom center front confirmation mark SAK11 and the bottom center back confirmation mark SAK10, which are minimally marked on the temporary unit sole of the pattern molding machine, refer to the center from the toe to the heel of the foot. The pattern molder creates a temporary unit sole so that it matches the center line of the foot, and whether the center line of the foot and the pattern molder match the center line has a great effect on the comfort of the shoe.
For these reasons, position confirmation marks such as the bottom center front confirmation mark SAK11 and the bottom center back confirmation mark SAK10 are required. With these minimum position confirmation marks, it is possible to check whether the foot, the paper pattern molding machine, and the footwear match, separately on the vertical and horizontal axes.

For the same reason, the upper of the footwear is marked with an inner MP1 toe confirmation mark SUH2 on the inside of the foot, an outer MP5 toe confirmation mark SGH3 on the outer side of the foot, a confirmation mark STH6 before the center of the instep, and a confirmation mark STH7 after the center of the instep at a minimum. Furthermore, for the same reason, a bottom center front confirmation mark SAH11 and a bottom center back confirmation mark SAH10 are minimally marked on the unit sole of the footwear.

In addition to the above-mentioned minimum position confirmation marks, the position confirmation marks of the paper pattern molding machine that correspond to the part where the foot was measured will be explained. The following six items correspond to this. Inner 1st toe nail confirmation mark SUK1, outer cuneiform bone confirmation mark SGK4, lateral base confirmation mark SGK5, outer heel confirmation mark SAK8, inner heel confirmation mark SAK9, 1st toe center confirmation mark SAK12.

First, the inner first toe nail confirmation mark SUK1 will be explained. This position confirmation mark is made by measuring the base of the nail of one toe. By aligning the edge of the upper with the base of the nail of the first toe, it prevents shoe chafing caused by the edge of the upper rubbing against the cuticle at the base of the nail. This can be confirmed with the confirmation stamp SUK1. It is possible to visually determine whether the upper edge is the base of the nail, so the inner first toe nail confirmation mark SUK1 is not absolutely necessary, but it can be used to improve wearing comfort.

Next, the external cuneiform bone confirmation mark SGK4 will be explained. This position confirmation mark is placed along the outside of the carapace with the cuneiform bone S4 as the base point. It is easier to measure by placing the mark on the outside of the foot, and having the mark on the outside has the advantage of being easier to see, but it may also be marked on the inside of the foot. Since the cuneiform bone has a convex shape, it rubs against the upper and is prone to shoe blisters. If the instep circumference of the upper, which passes through this point of the cuneiform bone, is short, the tightness will be strong and blisters will easily occur. On the other hand, if the instep is too long, it will float and tend to fall off when walking. The external cuneiform bone confirmation mark SGK4 is not absolutely necessary, as it is possible to visually determine whether the shoe is too tight or loose, but it can be used to improve wearing comfort.

Next, the outer basal part confirmation mark SGK5 will be explained. This position confirmation mark is placed at the base of the fifth metatarsal bone, which is located along the outside of the instep from the base of the ankle. When the heel lifts while walking, the edge of the upper rubs against the outside of the center of the foot, causing blisters. One way to prevent shoe blisters is to angle the end face of the upper as straight as possible from the instep to the ground. At this time, determine where in the direction of the ground the position should be by looking at the base of the fifth metatarsal bone. The outer base confirmation mark SGK5 is not absolutely necessary, but it can be used to improve wearing comfort.

Next, the outside heel confirmation mark SAK8 will be explained. This position confirmation mark is placed at the outer apex of the heel, which is likened to a circle. If the size of the dogleg on the foot and the unit sole do not match, the heel of the foot will stick out, making it uncomfortable to wear, but if there is a mark, the information can be quantified and improvements can be made. The external heel confirmation mark SAK8 is not absolutely necessary, but it can be used to improve comfort.

Next, the inner heel confirmation mark SAK9 will be explained. This position confirmation mark is placed at the inner apex position of the heel as a circle. The inner heel confirmation mark SAK9 is not absolutely necessary for the same reason as the outer heel confirmation mark SAK8, but it can be used to improve wearing comfort.

Next, the first toe center confirmation mark SAK12 will be explained. This position confirmation mark is placed at the center of the first toe. When a bunion develops, the first toe of the foot bends toward the second toe, but because it bends gradually, it is difficult for the person to notice.
If there is a mark, you can notice it early and take preventive measures. The first toe center confirmation mark SAK12 is not absolutely necessary, but it can be used to prevent foot deformity. In addition, the inner first toe nail confirmation mark SUH1, the outer cuneiform bone confirmation mark SGH4,
Regarding the outer base confirmation mark SGH5, the outer heel confirmation mark SAH8, the inner heel confirmation mark SAH9, and the first toe center confirmation mark SAH12,
Although it is not absolutely necessary for the same reason as mentioned above, it can be used to improve the comfort of your shoes.

The following position confirmation mark of the paper pattern molding machine, which is not explained above, will be explained. External 1st toe nail confirmation mark SGK1, external MP1 toe confirmation mark SGK2, internal MP5 toe confirmation mark SUK3, internal cuneiform bone confirmation mark SUK4, internal base confirmation mark SUK5. These position confirmation marks are located almost on the opposite side of the foot center line AT1 from the part where the foot was measured, and do not directly correspond to the part of the foot.
It is easier to determine if the angle of the wrinkles on the upper is diagonal if there is a mark, and this position confirmation mark can be used in such cases. It can also be used as a reference position when adjusting the cushion. Although it is not absolutely necessary, it can be used to improve the comfort of your shoes. Also, for the same reason as mentioned above, regarding the external 1st toe nail confirmation mark SGH1, the external MP1 toe confirmation mark SGH2, the internal MP5 toe confirmation mark SUH3, the internal cuneiform bone confirmation mark SUH4, and the internal base confirmation mark SUH5, which are marked on footwear. Although it is not absolutely necessary, it can be used to improve the comfort of your shoes.

According to the method of the first embodiment, by manufacturing a pattern molding machine exclusively for an individual according to the individual's foot, it is possible to provide footwear tailored to the foot with high precision. This method is suitable when a customer's foot has a unique shape, but there are problems in that it involves many manufacturing steps and is time-consuming. Moreover, after a paper pattern forming machine is used once, the user does not use it again, and in some cases, it is discarded, resulting in wasted materials. If a customer's feet are of average size, an average-sized paper pattern molding machine can be prepared and used, thereby eliminating the step of measuring the feet and producing a paper pattern molding machine. This method will be explained in Example 2.

In order to manufacture a pattern molding machine of an average foot size, it is necessary to know the average value of each part of the foot, as shown in FIG. 7 of Example 1. To find out the average value, there are two methods: use an average-sized wooden mold, and measure several people's feet to determine the average value.Use these methods to derive the required average value. Footwear is completed according to the procedure described using FIGS. 7 to 28 of Example 1 based on the average value of the feet.

The advantage of using the pattern forming machine described in Examples 1 and 2 is that the size of the footwear can be adjusted as a whole according to the size of the foot because of the structure in which multiple rows of suture holes can be freely selected. However, this method requires work costs because the pattern is drawn using a pattern maker. In Example 3, a method for manufacturing footwear without using a pattern molding machine will be described.

First, in the same manner as in FIGS. 1 to 7 of Example 1, the feet of an individual are measured and a recording sheet is drawn. Based on the recording sheet, FIG. 7, the foot is drawn in accordance with the procedures shown in FIGS. FIG. 9 can be used as it is as an insole pattern for footwear drawn by measuring an individual's feet. Next, the measurements of the instep part are carried out by the method explained in FIG. 12 of Example 1, and the drawings shown in FIGS. 13 and 14 are drawn. This figure 14 can be used as it is as an upper pattern for footwear drawn by measuring an individual's feet.

Next, a footwear unit sole and a footwear upper are manufactured based on the inner sole pattern in FIG. 9 and the upper pattern in FIG. 14, and then footwear is manufactured in accordance with the procedure described in FIGS. 24 to 28 of Example 1. Up to this point, we have explained the method of manufacturing footwear by measuring the foot without using a pattern molding machine. It can also be manufactured with different values and adjusted with cushioning material and foot circumference increasing members.

Note that the position confirmation mark of the present invention and the method of using seams and suture holes to function as scales can be used for all types of footwear, including footwear manufactured using a stitch-down method in which seams are provided on the outer periphery of the footwear.
