Abstract
A shoe sole is disclosed. To improve the gait flow of persons who have hip problems, the shoe sole has a contact damper in the heel area and additionally, in the forefoot area, has a rotary element which allows the foot to rotate outwards about a previously individually determined rotational axis in the forefoot area. The underside of the shoe sole remains at least locally in frictional contact with the ground below the rotary element. Preferably, the rotary element is designed as a torsion element consisting of a fiber bundle, the torsional axis of which is substantially perpendicular to the shoe sole.
Claims11
A shoe sole for an orthopedic shoe, comprising:
- a heel area;
- and
- a forefoot area;
- wherein the heel area has a contact damper and wherein the forefoot area has an elastically returning rotary element with an axis of rotation extending perpendicular to the shoe sole;
- wherein the rotary element has a base that connects to an underside of the shoe sole and wherein the rotary element allows at least for a limited external rotation of the shoe sole about the axis of rotation relative to the base;
- wherein a transverse extent of the rotary element is at least 30% smaller than a transverse extension of the shoe sole in the forefoot area such that a position of the rotary element is determinable in manufacturing the shoe sole between a position at an outer edge of the shoe sole and a position at an inner edge of the shoe sole;
- and wherein the rotary element is formed such that a resisting force against an external rotation is smaller than a resisting force against an inner rotation.
