ABSTRACT:
A method for making a shoe pad is composed of a first step in which a foot-shaped body is formed of a foamable material. A shoe tree of a heat-resistant material is used as an inner mold over which the foot-shaped body is fitted. The inner mold and the foot-shaped body are contained in a shoe-shaped outer mold, which is then heated to cause the foot-shaped body to foam. The outer mold is cooled to allow the foot-shaped body to take form of the shoe pad. Upon completion of the process of cooling the outer mold, the outer mold is opened to remove the shoe pad from the inner mold.
