SOLE OF SPORTS SHOES EXHIBITING GOOD RUNNING EFFICIENCY

摘要

An athletic shoe suitable for efficient running. A depression is formed in the rear foot portion which extends forward from the calcaneal bone and which does not contact the ground. A band-like area is provided in the middle foot portion extending in the front-rear direction in the central portion between the medial side and the lateral side of the shoe sole so as to be continuous with the depression. The reinforcement member and the midsole are provided in the middle foot portion so that the upper surface of the midsole less easily sinks downward due to a load from above on the medial side than in the band-like area and on the lateral side. In the front foot portion, a longitudinal groove is formed which extends in the front-rear direction in the central portion of the midsole body so as to be continuous with the band-like area. The longitudinal groove is curved so as to be generally parallel to the lateral edge of the front foot portion of sole.
