In this half shoe, the upper surface portion 110 made of natural leather having a soft and stretchable shoe body 100 and the lower surface portion 120 made of natural leather having soft and stretchable properties have an opening 130 at one

end side

110a, 120a. Each of the

edge portions

110b and 120b is sewn at a seam allowance of 2.5 mm so as to form a bag. The flat shape of the shoe body 100 is that the half on the thumb side and the half on the little finger side of the shoe body 100 are asymmetrical, and the thumb side is compared to the little finger side so that the shoe body 100 can softly wrap the entire toes. It is greatly formed. Further, the width W110 (see FIG. 5) of the upper surface portion 110 is formed to be larger than the width W120 (see FIG. 6) of the lower surface portion 120 so that W110> W120. The seam allowance is set to 2.5 mm, which is suitable considering as much as possible the reduction in load on the wearer's foot, particularly the toe, due to the seam. However, the seam allowance is not strictly limited to this 2.5 mm, and it is a matter of course that the shoe main body 100 can be manufactured with a slight numerical range.

The upper surface portion 110 and the lower surface portion 120 are made of natural leather with a thickness of about 0.4 mm that is soft and stretchable as natural leather. Since it is suitable in terms of easiness and easiness of sewing, it is the thickness, and is not limited to the thickness as long as it has an equivalent function. A generally used thickness of about 0.6 mm is sufficient if it has an equivalent function. Although artificial material having the same function as natural cow leather may be used, at present, natural cow leather is advantageous and practical in terms of cost and softness of the seam of the toe part. Natural pig leather and deer leather may be used, but since natural pig leather is thick, processing to make it thin and soft is necessary. Not suitable. Although natural deer leather is soft, it is easy to tear and has difficulty in durability and is expensive. Therefore, at present, natural cowhide is preferable because it is excellent in durability and inexpensive in terms of cost and has the merit that its performance varies depending on the processing method.

Further, the insole portion 140 attached to the lower surface portion 120 by adhesion of rubber glue is V-shaped from one end side to the other end side of the lower surface portion 120 (from the left side to the right side in FIGS. 3 and 6). It is sewed to the lower surface part 120 through the shape-like seam 150. The V-shaped seam 150 is formed such that when the shoe body 100 is attached to a foot, the insole portion 140 is formed on the lower surface portion against the force generated by the movement of the wearer with respect to the insole portion 140 and the lower surface portion 120 It functions so that it can hold the state firmly attached to 120.

Also, a cover 160 is sewn to the opening 130 on the upper surface 110 side of the shoe main body 100 through a seam 162 by gathering. The cover 160 is made of a two-way fabric having excellent extensibility and is designed. Moreover, this cover 160 is comprised so that the site | part located in the opening part 130 of the cyclic | annular rubber string (1st elastic body) 170 mentioned later may be coat | covered.

The annular rubber strap 170 is sewn to a part of the opening 130 on the upper surface 110 side of the shoe body 100 by gathering. Thus, the entire portion located in the opening 130 is configured to be covered with the cover 160 as described above. The rubber strap 170 may be configured to be sewn via the

seams

172 and 174 by gathering as shown in FIG.

Also, an annular rubber string (second elastic body) 180 is provided inside the opening 130 on the lower surface 120 side of the shoe body 100 by being sewn through the

seams

182 and 184 by gathering. ing.

Furthermore, a tag 190 having a deodorizing function is attached to the upper surface side of the insole portion 140 of the shoe body 100. The tag 190 is attached by sewing both end portions in the longitudinal direction to the insole portion 140.

As shown in FIG. 8, the cover 160 may be attached after the rubber string 170 is attached.

That is, first, the insole portion 140 is bonded to the upper side of the lower surface portion 120 with rubber glue (step S810 in FIG. 8). Next, by providing a V-shaped seam 150 with a sewing machine from one end 120a to the other end of the lower surface 120 (from the left side to the right side in FIG. 6), the insole portion 140 is The portion 120 is sewn (step S820 in FIG. 8). Subsequently, the rubber string 170 is sewn to the part where the opening 130 on the upper surface part 110 side is gathered with a sewing machine through the

seams

172 and 174 by gathering (step S830 in FIG. 8). Thereafter, the cover 160 is sewn to the part sewn in the opening 130 of the rubber cord 170 by gathering by providing a seam 162 with a sewing machine on the upper surface part 110 so as to cover the whole part (see FIG. 8 step S840). Thus, the upper surface portion 110 and the lower surface portion 120 are sewn into a bag shape by stitching the

respective edge portions

110b and 120b with a sewing machine at a sewing margin of 2.5 mm so as to form the opening portion 130 at the respective one

end portions
