## Abstract

Provided is a shoe including an upper composed of a fiber sheet, the fiber sheet including: a base sheet including yarns having heat shrinkability; and a plurality of chip members, each of which is a sheet having an area smaller than that of the base sheet, the base sheet and the plurality of chip members being layered and joined together.

## Claims

### Claim 1

A shoe comprising an upper composed of a fiber sheet, the fiber sheet comprising:
an inner layer comprising a base sheet comprising yarns having heat shrinkability; and
an outer layer comprising an aggregate of a plurality of chip members, each of which is a sheet having an area smaller than that of the base sheet and a polygonal shape or a circular shape having a side or a diameter from 10 mm to 50 mm, wherein
the base sheet and the plurality of chip members are layered and joined together,
exactly one of warps or wefts of the yarns of the base sheet have heat shrinkability, and
the yarns of the base sheet have fibers knitted or woven to have distances between adjacent intersections of the fibers of 1 mm to 5 mm.

### Claim 2 (depends on 1)

The shoe according to claim 1, wherein the plurality of chip members and the base sheet are integrated together by needle punching.

### Claim 3 (depends on 1)

The shoe according to claim 1, wherein the plurality of chip members are arranged at least on an outer side of the base sheet of the upper.

### Claim 4 (depends on 1)

The shoe according to claim 1, wherein a layer comprising any one of a non-woven fabric, a knitted fabric, and a woven fabric is provided on an inner side of the base sheet of the upper.

### Claim 5 (depends on 1)

The shoe according to claim 1, wherein each of the plurality of chip members is composed of any one of a non-woven fabric, a knitted fabric, and a woven fabric, and is made of a recycled material.

### Claim 6 (depends on 1)

The shoe according to claim 1, wherein the plurality of chip members partially overlap each other to join to the base sheet.

### Claim 7 (depends on 2)

The shoe according to claim 2, wherein the plurality of chip members are arranged at least on an outer side of the base sheet of the upper.

### Claim 8 (depends on 2)

The shoe according to claim 2, wherein a layer comprising any one of a non-woven fabric, a knitted fabric, and a woven fabric is provided on an inner side of the base sheet of the upper.

### Claim 9 (depends on 3)

The shoe according to claim 3, wherein a layer comprising any one of a non-woven fabric, a knitted fabric, and a woven fabric is provided on an inner side of the base sheet of the upper.

### Claim 10 (depends on 2)

The shoe according to claim 2, wherein each of the plurality of chip members is composed of any one of a non-woven fabric, a knitted fabric, and a woven fabric, and is made of a recycled material.
