Abstract: A shock-absorbing sole for a ski boot. The sole of the ski boot includes at least one elastically deformable element and at least one stiffener, which together comprise the shock absorption apparatus of the invention. The stiffener gives the sole its necessary rigidity for cooperation with the ski bindings. The elastically deformable element, on the other hand, absorbs forces that are encountered during skiing. The shock absorption apparatus can be included in a removable end plate so that the elastically deformable elements can be conveniently replaced to thereby permit the skier to insert an element having the properties he desires. The elastically deformable elements can be either flush with the lower surface of the sole or, alternatively, can be sandwiched within the thickness of the sole.

Abstract: There is provided a ski boot wherein a support element in the interior of the boot shaft acts on an inner boot in the area of the skier's instep. A pulling element forms a first partial loop which is guided across the front end region of the support element and extends from there against the sole of the boot and is reversed in the sole in a way such that its segments run into an adjustment nut from the back. A second partial loop is guided across the top end region of the support element and extends to guide elements of a heel cap and is guided from there with an intersection or cross-over to the adjustment nut. The nut is seated on a spindle which is rotatable by means of an adjusting motor. By displacing the nut in the lengthwise direction of the boot toward the toe, the size of the two partial loops is reduced, permitting the support element and the heel cap to come to rest against the inner boot and the latter to come to rest against the foot.
