Description

Shoe body structure with adjustable foot pressure and preparation method thereof

The present invention is related to a sole structure; in particular, it is related to a shoe body structure with adjustable foot pressure and a preparation method thereof.

According to research statistics, many patients have trouble with foot shape symptoms, such as flat feet, high arches or hallux valgus. Some of these are due to special congenital shapes, but most of them are due to acquired work environments and long-term poor personal postures, which lead to changes in foot shape. In severe cases, it may even affect pelvic deviation or scoliosis, causing symptoms of different lengths of the feet when moving (commonly known as long and short feet).

Since the soles of common shoes on the market, such as sports shoes, slippers or work shoes, can basically only provide cushioning and support functions, for the aforementioned patients, when walking or standing, it is easy for the center of gravity of the sole to be biased to a certain direction due to foot shape symptoms, such as the center of gravity biased to the inner side of the sole or the outer side of the instep, resulting in uneven pressure on the sole. Because of this, the sole function of the existing shoe cannot provide corresponding correction and support according to the patient's sole pressure distribution. In addition, the soles of a pair of existing shoes are usually designed to be symmetrical and of the same thickness. If the patient has symptoms of a difference in length of both feet due to movement, the soles of the existing pair of shoes cannot provide corresponding reinforcement support according to the length of the patient's feet.

In order to solve the defects of the existing shoes, many patients usually add corrective insoles to the soles to correct and adjust the above-mentioned foot symptoms to improve the problem of uneven pressure on the soles of the feet, making it more comfortable for the patient to wear and walk, and even customizing the thickness of the insoles to suit the length difference of the two feet.

However, the aforementioned corrective insole is not only expensive to manufacture, but also serves as an auxiliary accessory of the sole in actual application, and cannot be used alone for walking. Moreover, the aforementioned corrective insole is further limited in application by the shape of the sole. For example, if the shoe body is a flip-flop, the aforementioned corrective insole is difficult to be placed on the sole due to the flip-flop protrusions on the upper, and may even be easily lost. Therefore, the aforementioned corrective insole has the above defects and troubles in use.

In view of this, the purpose of the present invention is to provide a shoe body structure with adjustable foot pressure and a preparation method thereof, which can provide enhanced support performance corresponding to the user's foot pressure distribution or gait posture by installing a support unit in the foam sole. The foam sole has more freedom and wide application, and can also save the cost of other shoe accessories.

In order to achieve the above-mentioned purpose, the present invention provides a shoe body structure with adjustable foot pressure, including a foam sole and a support unit. The foam sole has a sole section, a heel section, and an arch section located between the sole section and the heel section. The foam sole has a mounting area located at least one of the sole section, the heel section or the arch section, and the mounting area has a plurality of concave holes; the support unit is arranged in the mounting area of the foam sole and can be interchangeably combined in the concave holes, wherein the rigidity of the support unit is greater than the rigidity of the foam sole.

Another embodiment of the present invention provides a shoe body structure with adjustable foot pressure, including a foam sole and a support unit. The foam sole has a sole section, a heel section, and an arch section located between the sole section and the heel section. The foam sole has a mounting area located in at least one of the sole section, the heel section or the arch section; the support unit is hidden in the mounting area of the foam sole, and the rigidity of the support unit is greater than the rigidity of the foam sole.

Another embodiment of the present invention provides a method for preparing a shoe body structure with adjustable foot pressure, comprising the following steps: step S1, providing a foam sole, wherein the foam sole is located on at least one of a sole section, a heel section or an arch section and defines a mounting area; and step S2, installing a support unit in the mounting area of the foam sole, wherein the rigidity of the support unit is greater than the rigidity of the foam sole, and is used to support the sole pressure.

The effect of the present invention is that the shoe body structure with adjustable foot pressure of the present invention utilizes the difference in physical properties between the support unit and the foam sole, so that when the support unit is set on the foam sole, the support unit can strengthen the support of the foam sole, thereby providing the effect of improving and correcting the pressure on the sole of the foot, so that the pressure on the sole of the user can be balanced, thereby improving the comfort of walking on the sole of the foot, and the shoe body structure with adjustable foot pressure does not need to be additionally configured with a conventional corrective insole on the foam sole, in addition to saving the cost of other shoe accessories, making the foam sole more free and extensive in application.

In addition, the preparation method of the shoe body structure with adjustable foot pressure in this embodiment can be customized to preset support units of different physical properties on the installation area of the foam sole according to the standing habits or sole pressure distribution of different users, so that the sole of the user can get better correction assistance.

In order to explain the present invention more clearly, a preferred embodiment is given and described in detail with drawings as follows. Please refer to Figures 1 to 3, which are the first preferred embodiment of the present invention, showing the basic structure of the shoe body structure 100 with adjustable foot pressure.

The adjustable foot pressure shoe body structure 100 provided in the first embodiment basically comprises a foam sole 10 and a support unit 20, wherein the foam sole 10 is a solid foam body, which is integrally injection-molded from a foam material. The foam sole 10 can be applied to various finished shoes, including sports shoe soles or slipper soles, etc.; the support unit 20 can be replaceably installed on the foam sole 10.

Please refer to Figures 1 and 3. The shape of the foam sole 10 corresponds to the shape of a human foot, and has a sole section 11, a heel section 12 and an arch section 13. The arch section 13 is located between the sole section 11 and the heel section 12. The foam sole 10 has a mounting area T located at least one of the sole section 11, the heel section 12 or the arch section 13, and the mounting area T is pre-set with a plurality of concave holes 14. In this embodiment, Figures 1 to 3 show that the mounting area T is defined on the sole section 11 and the heel section 12, and the mounting area T is located on the sole surface 15 of the foam sole 10, wherein the mounting area T is pre-set with a plurality of first concave holes 14a on the sole section 11, and the mounting area T is pre-set with a plurality of second concave holes 14b on the heel section 12.

Referring to FIGS. 1 and 3 , the opposite sides of the sole section 11 have a first medial edge 111 and a first lateral edge 112, and the sole section 11 defines a first flat portion between the first medial edge 111 and the first lateral edge 112. In this embodiment, the number of the first concave holes 14a is designed to be six, of which three first concave holes 14a are arranged on one side of the sole section 11 corresponding to the first medial edge 111, and the other three first concave holes 14a are arranged on the sole section 11 corresponding to the first lateral edge 112. The other side of the heel segment 12; the opposite sides of the heel segment 12 have a second medial edge 121 and a second lateral edge 122, and the heel segment 12 defines a second flat portion between the second medial edge 121 and the second lateral edge 122. In this embodiment, the number of the second recessed holes 14b is designed to be six, of which three second recessed holes 14b are arranged on one side of the heel segment 12 corresponding to the second medial edge 121, and the other three second recessed holes 14b are arranged on the other side of the heel segment 12 corresponding to the second lateral edge 122. For the convenience of explanation, Figures 1 and 3 show that the number of the first recessed holes 14a and the number of the second recessed holes 14b are the same.

In other embodiments, the preset positions of the first concave hole 14a and the second concave hole 14b can be adjusted according to the foot pressure requirements of the user, as long as the first concave hole 14a is arranged on both sides of the sole section 11 corresponding to the first medial edge 111 and the first lateral edge 112 of the first foot blade, and the second concave hole 14b is arranged on both sides of the sole section 11 corresponding to the second medial edge 121 and the second lateral edge 122 of the second foot blade; the number of the first concave hole 14a and the second concave hole 14b can be adjusted. For example, in the sole section 11, the number of the first concave holes 14a of the first medial edge 111 and the number of the first concave holes 14a of the first lateral edge 112 of the first instep may be different from each other, or the first concave holes 14a may be arranged only on one side of the sole section 11; in addition, the installation area T of the foam sole 10 is not limited to being located on the sole surface 15, but may also be located on the treading surface of the foam sole 10 (not shown in the figure), and the installation area T may be preset at the arch section 13 of the foam sole 10.

The support unit 20 is disposed in the mounting area T of the foam sole 10, and the support unit 20 can be interchangeably combined in the concave holes 14, wherein the rigidity of the support unit 20 is greater than that of the foam sole 10, and is used to support the pressure on the sole of the foot.
