## Abstract

A shoe and a corresponding method for making a shoe are disclosed. A shoe according to an embodiment includes: an upper including a main body; a midsole, an outside edge of the midsole being attached to a lower edge of the main body, the midsole being formed to define a first accommodation space; and a first fill injected in the first accommodation space.

## Claims

### Claim 1

A shoe, comprising:
an upper comprising a main body, the main body being provided with an extension, such that an upper rim of the extension is attached to the main body, and the extension overlaps a lower part of the main body;
a midsole; and
an insole located on an upper side of the midsole;
wherein the midsole comprises a fill that occupies a space comprising a first space defined between a wrapped-around portion of the extension and the insole and a second space defined between the extension and the lower part of the main body overlapped by the extension.

### Claim 2 (depends on 1)

The shoe as claimed in claim 1, further comprising an outsole attached to and covering a bottom surface of the midsole.

### Claim 3 (depends on 1)

The shoe as claimed in claim 1, wherein the insole comprises a first fabric layer and a first leakage-preventing film attached to a lower side of the first fabric layer to prevent leakage of said fill.

### Claim 4 (depends on 1)

The shoe as claimed in claim 1, wherein the main body comprises a second fabric layer and a second leakage-preventing film attached to the second fabric layer to prevent leakage of said fill.

### Claim 5 (depends on 1)

The shoe as claimed in claim 1, wherein the main body comprises a front portion and a back portion attached to each other, and the back portion is formed by molding.

### Claim 6 (depends on 1)

The shoe as claimed in claim 1, wherein the extension includes a fabric layer and a leakage-preventing material attached to and covering the fabric layer.

### Claim 7 (depends on 1)

The shoe as claimed in claim 1, wherein the fill is a thermoset material made of polyurethane or polyurethane foam.

### Claim 8 (depends on 1)

The shoe as claimed in claim 1, wherein the space which said fill occupies is shaped by molding.
