[0064] 3 to 7 show the first embodiment. What Fig. 3 showed is the inner side of the shoe (right foot) of the first embodiment, and Fig. 4 shows its outer side. In addition, in Figure 3- Figure 6 In , in order to facilitate understanding of the installation position of the expansion and contraction parts, the expansion and contraction parts are shaded.

[0065] As shown in FIG. 3 , the shoe includes a sole S and an upper U.

[0066] The shoe upper includes a first opening 1 , a second opening 2 , an outer telescopic portion 50 , an inner telescopic portion 51 , a front portion 3 and a rear portion 4 .

[0067] Such as Figure 5 As shown, the above-mentioned first opening 1 and second opening 2 are arranged in the center of the vamp U. The first opening 1 is the opening over which the foot protrudes when the shoe is worn. The second opening 2 is closed by the tongue T. As shown in FIG. The first opening 1 is located behind the second opening 2 and is connected to the sec...

[0103] 8 and 9 show a second embodiment of the shoe of the present invention. Fig. 8 shows the inner side of the shoe (left foot), and Fig. 9 shows the outer side thereof. In addition, in FIG. 8 and FIG. 9 , in order to facilitate understanding of the installation location of the telescopic part, grids are drawn on the telescopic part. In addition, in the following embodiments, the same reference numerals are given to the same parts as those of the first embodiment or corresponding parts, and detailed descriptions and illustrations thereof will be omitted.

[0104] As shown in FIG. 8 , in the present embodiment, the above-mentioned elastic member 56 of the inner expandable portion 51 is divided in the vertical direction.

[0105] In addition, as shown in FIG. 8 , the first inner portion 61 is formed in a bifurcated shape. Furthermore, as shown in FIG. 9 , the outer eyelet modification portion 72C extends to the upper surface of the sole S at the rear of the foot.

[0107] Figure 10 shows a third embodiment of the shoe of the present invention. Fig. 10(a) is a perspective view of the inner telescopic part and its vicinity in this embodiment, and Fig. 10(b) is an exploded perspective view of this part.

[0108] In this embodiment, as shown in FIG. 10( a ), the ring P covers the above-mentioned inner cutout portion 63 . As shown by the dotted line, both ends of the ring P are sewn to the upper ends of the first inner portion 71 and the second inner portion 61 , but are not sewn to the eyelet modification portions 62 , 72B. Therefore, the ring P allows the expansion and contraction operation of the above-mentioned inner expansion and contraction portion 51 .

[0109] Moreover, as shown in the exploded perspective view of FIG.10(b), each part 61,62 of the front part reinforcement material 6, and each part 71,72B of the rear part reinforcement material 7 form a mutually different entity. The upper ends of the respective inner portions 61 , 7...

Abstract

The present invention provides an upper part (U) of each of sports shoes having a first opening (1) surrounding the instep of a foot and allowing the foot to be upwardly projected therethrough when the sports shoes are worn and a second opening (2) closed by a tongue piece (T) which are arranged continuously to each other, comprising an inside extension part (51) covering a part of the inner surface of the plantar arch of the foot, an outside extension part (50) covering a part of the outer surface of the hypothenar of the foot, a front part (3) disposed at the front of the both extension parts (50) and (51), and a rear part (4) disposed at the rear thereof. The extension parts (50) and (51) cross one side-face of the upper part (U) starting at the upper surface of a sole (S) to the second opening (2). The Young's Modulus of the extension parts (50) and (51) in the foot longitudinal direction (L) is set smaller than the Young's Moduli of the front part (3) and the rear part (4).

Description

technical field [0001] The present invention relates to sports shoes with improved comfort of the upper. Background technique [0002] In general, uppers are designed with the shape of the foot in mind when at rest. The shape of the foot during exercise often changes inside the shoe. That is, during exercise, the upper sometimes cannot keep up with the deformation of the foot and separates the sole from the foot, or sometimes the upper restricts the natural deformation of the foot. Therefore, the shoe upper is considered as a part that makes the sole follow the foot, and at this time, it is desirable that the shoe upper deforms following changes in the shape of the foot during exercise. [0003] That is, since the feet are deformed during walking, shoes are required to have good comfort for the feet. In order to improve the above-mentioned comfort, the deformation distribution of the upper is preferably close to the deformation distribution of the foot. [0004] As shoes...
