ABSTRACT:
In a shoe sole, in particular for athletic shoes, that is assembled at least from an outsole and a cushioning midsole, where the midsole has recesses extending essentially perpendicular to the plane of the sole, to improve the comfort of such a shoe and to increase the dimensional stability of the sole parts, the midsole is formed of a first midsole element (1a) consisting of a compact thermoplastic material and a second midsole element (2a) consisting of a foamed plastic material. Recesses (3) are distributed at least predominantly over the entire first midsole element (1a) made of compact thermoplastic material and are closed on a side facing away from the second midsole element (2a). Additionally, the second midsole element (2a) is injected onto the first midsole element (1a) closing open ends of the recesses and optionally, partially penetrating the recesses and/or encapsulating stabilizing inserts disposed in the arch area of the first midsole element.
