ABSTRACT:
A process of making a shoe includes bonding a flat structure to an upper layer of the shoe to form a bonded structure. The flat structure has a melting temperature T.sub.2 and provides stability to a shape of the upper layer. The bonded structure is positioned into a mold so that an underside of the bonded structure faces the mold. A liquid sole material at a temperature T.sub.1 which is greater than T.sub.2 is sprayed into the mold, thereby contacting and melting the flat structure. The sole material cools and solidifies to form a shoe. The flat structure has a melting temperature T.sub.2 and provides stability to a shape of the upper layer.
