Abstract
A running shoe comprising a front sole of hard plastic material for mounting gripping elements, and a support member arranged behind the rearmost gripping elements, of elastically deformable material. In order to ensure that it is better possible to maintain a foot attitude required for optimum running efficiency, the support member is a wedge member which increases in thickness in a rearward direction and which comprises a relatively hard but elastically pressure-deformable material, wherein the underside thereof is disposed approximately in one plane with the front sole, and the wedge member extends at least with its portion associated with the outer edge of the sole, into the shank region of the sole.
