Abstract: A running shoe sole has an elastically deformable supporting sole, which has a rear and front foot section connected to each other via a coupling section. An elastically deformable supporting device is arranged on the supporting sole and carries an outsole covering. The supporting device includes a rear foot part which engages around the rear foot section of the supporting sole in a U shape and a front foot part having two limbs which are arranged on mutually opposite lateral edge sections of the front foot section. The rear and front foot part each have a supporting surface, which runs obliquely inward toward the underside of the shoe sole or is curved, preferably convex, and on which the supporting sole rests and is supported in the lateral direction. The rear and front foot parts are made from a highly responsive thermoplastic elastomer of 45-50 Asker Shore C density.
