Abstract
Abstract A shoe, especially a sport shoe, with a shoe sole, which is composed of an outsole, a midsole of elastically springy material and an insole, and a honeycomb body with cell walls oriented approximately perpendicular to the shoe outsole, is improved so that additional damping, especially at the moment that the shoe sole engages on the ground is made possible. This is achieved in that a honeycomb is incorporated into the midsole, as a part of the midsole itself or as a sole part connected or inserted in the midsole has cell walls that are gas-permeable so as to enable gas to be exchanged between adjacent honeycomb cells.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
97 words
In a shoe of the type having a shoe sole which is composed of an outsole, a midsole having a body formed of elastically springy material, an insole, and a honeycomb body with self-supporting cell walls oriented at least approximately perpendicular to an outer surface of the outsole, said honeycomb body being incorporated within the body of the midsole, the improvement wherein the cell walls are constructed in a manner enabling a gas exchange between each pair of adjacent honeycomb cells through each cell wall between them as a means for producing a controlled air cushion effect.
Claim 2
Dependent Claim
