1 Claim.

This invention relates to shoe construction, and more particularly to the construction of shoes of the open or sandal type.

The primary object of the invention is to provide a shoe of this character wherein the upper is constructed of semirigid tubular sections secured to the inner shoe sole by means of a cord formed preferably of plastic material, the securing cord being successively extended through the adjacent tubular sections, whereby the tubular sections of the upper are held to the inner sole and arranged in close engagement with respect to each other, in the formation of the shoe upper.

Another object of the invention is to construct a tubular section of various colored plastic material, whereby various color schemes may be carried out in the manufacture of novelty shoes.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel steps in the method and certain details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the method disclosed and in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a plan View of a shoe upper constructed in accordance with the invention.

Figure 2 is a side elevational view thereof.

Figure 3 is a sectional View taken on line 3 3 of Figure 1.

Referring to the drawings in detail the inner sole of a shoe is indicated by the reference character 5, to which the tubular section of which the upper is constructed are secured.

The reference character 6 indicates tubular sections forming the upper of the shoe, the tubular sections being preferably constructed of plastic material and colored in such a way that when the tubular sections are secured in the construction oi the upper various color schemes may be carried out. The sections 6 are formed by spirally twisting lengths of plastic material to form tubes to the end that the tubular sections will be flexible and may be readily formed into loops.

As shown, these tubular sections are of varions lengths, so that in the construction of the upper the tubular sections are reduced in height, toward the toe of the shoe so that the shoe will properly fit the foot of the wearer.

The tubular sections are secured by means of the cord 1 which is preferably constructed of afs-11.5)

plastic material, the cord 'l being shown as extended through openings in the inner sole and tied, securing one end of the securing cord to the inner sole. 'I'he cord is now extended upwardly through one of the end tubular sections 6, and is then passed through the inner sole 5, then back through the inner sole and extended through the adjacent tubular section 6. This securing cord 'l is successively threaded or laced through the sole and tubular section, as clearly shown by Figure 3 of the drawing, the other end of the cord being secured to the inner sole by tying.

It will be seen that these tubular sections are disposed at acute angles with respect to the side edges of the inner sole to enhance the beauty of the shoe.

Because these tubular sections are held into close engagement with respect to each other, a strong and durable upper is provided, which is exceptionally cheap to manufacture.

The heel portion of the shoe is formed by using plastic cord as described, and passing one end of the plastic cord through the inner sole at a point in spaced relation with the rear end of the inner sole and tying the end of the cord at a point above the inner sole. The cord is now threaded through one of the plastic tubular sections and formed into an upstanding loop. The cord is now passed through the inner sole at the heel and then back up through the inner sole at a point spaced from the point where the cord was passed through the inner sole at the heel. The portion of the cord now extended upwardly through the inner sole is formed into a loop and threaded through another tubular section, which of course takes the curvature of the cord and the end of the cord is now passed through the inner sole at a point spaced from the rear end of the heel, and passed upwardly again through the sole where it is tied in such a way that the tubular section will house the knot and obscure it from View.

The flexible cord forming the heel is indicated by the reference character 8, and the tubular sections through which the cord 8 is threaded are indicated by the reference character 9. A cord indicated at IIJ secures the tubular sections 9 together at a point in spaced relation with the inner sole to close the back of the heel of the shoe.

The inner sole may now be secured to the outsole and heel of the shoe by stitching or otherwise, to complete the shoe.

Although I have shown and described these 3 tubular sections as being disposed at acute angles with respect to the edges of the sole, it is to be understood that the arrangement and angles at which these tubular sections are placed, may be varied in the formation of Various designs, within the scope of the invention.

Having thus described the invention, what is claimed is:

In a shoe construction, a sole, a plurality of exible tube members formed into loops extended above the sole, said loops being arranged in contact with each other side by side and being disposed at oblique angles with respect to the side edges of the sole in the formation of the shoe upper, the ends of the loops being open and resting on the sole adjacent to the side edges thereof,

a thread having its ends secured to the sole, the v' intermediate portion of the thread being extended through the loops, the portions of the thread between adjacent loops and at the ends of the loops being laced through openings formed in the sole, securing the loops to the sole,
