All-purpose ski boot for walking and skiing - has adjustable angle formed by insert to alter sole plane

摘要

The ski boot has an adjustable angle between the sole plane formed by the tread face of the heel (5) and the tread face of the sole part (1) beneath the ball of the foot and the tread plane. The tread plane consists of the plane of the ski or the plane of the ground. The sole (1) of the boot has at least one downwardly open trough-like cavity containing a tread body (4) which can be pushed in and out so that the lower face of the tread body (4) concides in its pushed-in position with the plane of the boot sole. In the extended position the tread body (4) forms together with the heel part (5) of the boot a tread plane which is suitable for walking so as to prevent strain on the person's knees, ankles and heels.
