Abstract A sole-heel assembly for women shoes, particularly of the high heel type, made of a plastics material, is described, which is formed of a single piece and is provided, inwardly with respect to the heel, with a reinforcing core having a hole for the fixing of the heel top-piece. A stiffening element is embedded in the sole and extends from the top of the heel as far as the overall front part of the foot-sole. The heel is laterally and rearwardly covered by a thin sheet material. The heel is covered on the front face by a further thin sheet material. The thin sheet material consists of skin, synthetic skin, wood or plastics laminate, and the reinforcing core and stiffening element are made of wood, metal, premolded plastics material or the like. The method of preparation consists of injection molding a thermoplastics material in a mold formed by opposed complementary portions defining therebetween a cavity of the proper shape for the heel and sole, and embedding a reinforcing core and a stiffening element respectively in the heel and sole during the injection step. A thin sheet material for laterally, rearwardly and frontwardly covering the heel is located in the mold at the heel cavity before the injecting of the thermoplastics material.
A method of preparing a one-piece sole-heel assembly of the high heel type which consists of the steps of (1) placing a thin sheet material in a mold formed by opposite complementary portions defining therebetween a cavity of the proper shape of the heel and sole, for laterally, rearwardly and frontwardly covering the heel, (2) introducing into the mold a reinforcing core into the heel portion (3) introducing a stiffening element into the sole portion projecting from the top of the heel up to the overall front part of the sole (4) injecting a thermoplastic material into said mold through an opening above the heel portion, pressing said sheet against the mold inner face, whereby said reinforcing core and said stiffening element remain embedded in the heel and sole respectively.
