1. An artificial foot, comprising:
a length, a width, a height, and a longitudinal axis extending from a heel area to a toe area;
a connection member adapted to receive a lower leg part;
an upper support structure projecting downwardly and forwardly from the connection member;
an elastic sole structure extending from the heel area to the toe area, the sole structure being more elastic than the upper support structure;
an elastic element arranged between a heel-side end of the upper support structure and the elastic sole structure; and
a coupling system which is arranged at a toe-side end of the upper support structure and connects the upper support structure to the sole structure at a middle region along the length of the artificial foot, the coupling system establishing a distance between the upper support structure and the sole structure when no weight is placed on the artificial foot;
wherein the coupling system is configured to:
provide relative tilting motion between the upper support structure and the sole structure;
maintain constant the established distance between the upper support structure and the sole structure in a middle of the coupling system when a user places weight on the coupling system in a standing position;
transfer forces from the lower leg part to the sole structure in a portion of the artificial foot where the coupling system connects the upper support structure to the sole structure; and
maintain constant contact with both the upper support structure and the sole structure during use.
