ABSTRACT:
The ski boot shall allow an as convenient as possible walking on the ground surface and also a stable standing on the ground surface. To this end the heel and the sole of the boot are provided individually with a roll off area. When the ski boot rolls off on the ground surface, the two roll off areas combine. To this end the center of the radius on the roll off area of the heel is located in the area of the ankle. The center of the radius of the roll off area located at the sole of the shoe lies in the center of the knee joint. When walking with this boot, a rising and downwards movement of the ankle is avoided. Accordingly, the ski boot comprises a stable standing area which stabilizes the body when it stands. During the walking, the position of the center of gravity of the weight of the body is altered automatically such that the standing area cannot form a standing plane. Conclusively, the rolling off movement during walking is a smooth movement.
