## Abstract

A manufacturing method of a waterproof and breathable shoe has a step of preparing a mold. Then, the mold is soaked into the rubber material, and the rubber material can cohere to a surface of the mold. Then, the rubber material cohering to the surface of the mold is dried to form into a thin and integrally molded shoe body on the surface of the mold. Then, an inside layer is combined with the shoe body. Then, the inside layer and the shoe body are reversed inside out and stripped off from the mold at the same time. Finally, the sole is combined with a bottom of the shoe body to form the waterproof and breathable shoe. Therefore, the shoe can provide a waterproof and breathable effect.

## Claims

### Claim 1

A manufacturing method of a waterproof and breathable shoe having steps of:
preparing a mold;
soaking the mold into a rubber material, and the rubber material cohering to a surface of the mold;
drying the rubber material on the surface of the mold, and the rubber material being dried to form into a thin and integrally molded shoe body on the surface of the mold;
combining an inside layer with the shoe body;
reversing the inside layer and the shoe body and stripping the inside layer and the shoe body off from the mold at the same time; and
combining a sole with a bottom of the shoe body.

### Claim 2 (depends on 1)
