Abstract
Shoe sole for sport shoes with an outsole and a midsole of volume-compressible foamed material, as well as air cushions provided in the midsole is designed so that, on the one hand, the damping and, on the other hand, the restoring force, of the shoe sole, and thus the energy gain after release of the pressure from the shoe sole, is clearly improved. This is achieved in that the midsole (1) in the central area (2) under the heel bone (3), is provided with a honeycomb structure with individual honeycomb cells (4) that are integrally formed as part of the midsole (1) so as to open in a downward direction. These honeycomb cells (4) are sealed at their underside by an elastic cover (6).
