Abstract
A shoe, especially a sport or rehabilitation shoe with a shoe sole with at least one insert part formed of a honeycomb body of elastic compressible material, and having honeycomb cells of which the central axes run at least approximately perpendicular to the plane of the sole provides the honeycomb cells, in an area under the heel bone, in a central portion of the honeycomb body with a greater surface area, when seen in top view, than honeycomb cells surrounding the central portion. Thus, the central part of the honeycomb body represents the actual damping part, while the edge area surrounding it, acts as a support for the heel edge part, having a controllable stiffness or restoring force. Furthermore, the surface area of the honeycomb cells decreases in radially outward directions from the center, and preferably, the honeycomb cells are arranged in rings about a largest central cell with the honeycomb cells of the rings being elongated in a circumferential direction about the central cell.
