Abstract

A method of manufacturing a shoe includes preparing a flexible shell having an internal space, preparing an upper body in a form of a bag, the upper body being provided with an opening in a portion corresponding to a topline, preparing a sole body, accommodating the upper in the shell, partially fixing the shell and the upper body, and forming the upper body with a last being located in the upper body accommodated in the shell, taking the last out of the formed upper body, and inserting the sole body in the shell.

First claim

What is claimed is:

1 . A method of manufacturing a shoe, the method comprising:
preparing a flexible shell having an internal space; preparing an upper body in a form of a bag, the upper body being provided with an opening in a portion corresponding to a topline; preparing a sole body; accommodating the upper body in the shell; partially fixing the shell and the upper body in a portion of the upper body adjacent to the opening and in a portion of the shell adjacent to the topline through which a foot of a wearer is inserted; forming the upper body with a last located in the upper body; taking the last out of the formed upper body; and accommodating the sole body in the shell; wherein the partially fixing the shell and the upper body is performed after the forming the upper body; wherein in the preparing of the shell, the shell is made to consist of a single bag-shaped member including a bottom wall portion and a peripheral wall portion extending upward from a peripheral edge of the bottom wall portion to the topline, the bottom wall portion of the shell defining an outermost surface of the shoe located on a lower side of the shoe in the vertical direction; and wherein an outer surface of the bottom wall portion of the shell is a tread of the shoe.

2 . The method of manufacturing a shoe according to claim 1 , wherein
the accommodating the upper body in the shell is performed after the forming the upper body and before the partially fixing the shell and the upper body.

3 . The method of manufacturing a shoe according to claim 2 , wherein
the accommodating the sole body in the shell is performed after the partially fixing the shell and the upper body.

4 . The method of manufacturing a shoe according to claim 2 , wherein
the accommodating the sole body in the shell is performed before the accommodating the upper body in the shell.

5 . The method of manufacturing a shoe according to claim 1 , wherein
the upper body comprises a heat-shrinkable member, and in the forming the upper body, the upper body is thermally shrunk by being heated such that the upper body has an inner geometry in conformity with the last.

6 . The method of manufacturing a shoe according to claim 1 , wherein
in the partially fixing the shell and the upper body, the shell and the upper body are fixed by sewing.

7 . The method of manufacturing a shoe according to claim 1 , wherein
in the preparing the shell, the shell is provided with an engaging portion in a form of a wire or a band, in the preparing the upper body, a hole is provided in the upper body, and in the partially fixing the shell and the upper body, the shell and the upper body are fixed by engaging the engaging portion with the hole by inserting the engaging portion through the hole.

8 . The method of manufacturing a shoe according to claim 1 , wherein
in the preparing the shell, the shell is provided with a hole, in the preparing the upper body, the upper body is provided with an engaging portion in a form of a wire or a band, and in the partially fixing the shell and the upper body, the shell and the upper body are fixed by engaging the engaging portion with the hole by inserting the engaging portion through the hole.

9 . The method of manufacturing a shoe according to claim 1 , further comprising preparing a locking element that locks the shell and the upper body, wherein
in the partially fixing the shell and the upper body, the shell and the upper body are fixed by locking the shell and the upper body with the locking element.

10 . The method of manufacturing a shoe according to claim 1 , wherein
in the accommodating the sole body in the shell, the sole body is arranged on an inner side of the upper body in the internal space.

11 . The method of manufacturing a shoe according to claim 1 , wherein
in the accommodating the sole body in the shell, the sole body is arranged between a bottom wall portion of the shell and a bottom portion of the upper body in the internal space.

12 . The method of manufacturing a shoe according to claim 11 , wherein
in the preparing the shell, the shell is made such that the bottom wall portion includes a projection that projects into the internal space, in the preparing the sole body, the sole body is made to include a recess in a lower surface, and in the accommodating the sole body in the shell, the shell and the sole body are positioned by inserting the projection in the recess.
