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.
