Abstract
An athletic shoe, particularly a tennis shoe, with wear-resistant parts provided in the area of the outsole to increase the wear resistance of the sole material. The wear resistance of the outsole, particularly in the toe area or in other peripheral areas of the outsole, is significantly increased and yet a sufficient braking effect is maintained by the material of the outsole or of the edge of the outsole. This is achieved by molding parts made of one of such materials as an oxide ceramic, metal carbide, metal nitride or hard metal into the outsole in an upwardly directed edge (3) of toe area (4) of outsole (2) or by subsequently inserting them into the outsole in such a way that the outer surface of the parts ends approximately flush with an outer side of the edge surface of outsole.
