Abstract
The invention relates to a sliding element for a shoe sole. The sliding element includes an upper sliding surface and a lower sliding surface, wherein the lower sliding surface is arranged below the upper sliding surface so as to be slideable in at least two directions. The upper sliding surface can form a lower side of an upper sliding plate and the lower sliding surface can form an upper side of a lower sliding plate. A relative sliding movement between the upper sliding surface and the lower sliding surface distributes the deceleration of the shoe sole over a greater time period and allows the foot to feel as if it is wearing a conventional shoe that contacts a surface with reduced friction, for example, a soft forest ground. As a result, the force acting on the wearer and the momentum transfer on his or her muscles and bones are reduced.
