Abstract
An artificial foot having a longitudinal axis extending from a heel area to a toe area, a length, a width and a height is provided. The artificial foot includes a connection to a lower leg part, an upper supporting structure in the direction of height, an elastic sole structure extending from the heel area to the toe area, an elastic connecting element arranged between the upper supporting structure and the sole structure, and a coupling system. The upper supporting structure is connected to the sole structure approximately in a middle of the foot with respect to its length by means of the coupling system. The coupling system allows a relative tilting motion between the upper supporting structure and the sole structure while keeping a distance between the upper supporting structure and the sole structure in a middle of the coupling system constant, at least while a patient places weight on it when standing.
