Abstract
A shoe includes an upper that covers the instep of a foot. A hole that has a bottom and is recessed in the thickness direction of the upper is integrally formed in the upper. A bottom portion of the hole is one layer including at least two linear members that differ in stretchability.
Claims9
A shoe comprising an upper that covers an instep of a foot,
- wherein a hole that has a bottom and is recessed in a thickness direction of the upper is formed integrally in the upper, and
- a bottom portion of the hole is a single layer including at least two linear members,
- wherein a difference in Young's modulus between the materials of the two linear members is 5 percent or larger, and
- wherein the upper includes a peripheral portion having two layers disposed around the bottom portion, part of the linear members being one of the two layers, the remaining part of the linear members being the other one of the two layers.

- wherein each of the linear members has portions alternately protruding in one direction and the other direction in the thickness direction, and
- the upper includes:
- the bottom portion in which the linear members overlap each other in the thickness direction, to form one layer;
- a peripheral portion that is disposed around the bottom portion, and has two layers, part of the linear members being one of the two layers, the remaining part of the linear members being the other one of the two layers;
- and
- a base portion including:
- a two-layer portion in which part of the linear members is one layer, and the remaining part of the linear members is the other layer;
- and a portion in which the linear members intersect with each other.
