Abstract
A method for manufacturing a foam shoe material includes the following steps. (a) A plate prototype is formed, wherein the plate prototype is composed of thermoplastic polyurethane. (b) The plate prototype is foamed by a supercritical fluid to form a foam shoe material including a plurality of microporous structures and an average aperture of the microporous structures is smaller than 100 micrometers.

A method for manufacturing a foam shoe material, comprising:
- (a) heating thermoplastic polyurethane grain to form a liquid thermoplastic polyurethane;
- (b) infusing the liquid thermoplastic polyurethane into a shaping mold for forming the liquid thermoplastic polyurethane into a plate prototype;
- (c) moving the plate prototype to a foaming mold;
- (d) introducing a supercritical fluid into the foaming mold and mixing the supercritical fluid into the plate prototype;
- and
- (e) cooling the foaming mold and introducing the supercritical fluid out to allow the plate prototype foaming to form the foam shoe material.
