Abstract

A fit and support system for sports footwear, particularly for ski boots, comprises up to three separate supports. A lower support is shaped and dimensioned to bear evenly against the dorsal or upper surface of the foot, including the medial and lateral aspects thereof, forwardly of the ankle joint to permit unrestricted dorsiflexion of the foot at the ankle joint within the normal range. The support is sufficiently firm to transmit pressure from the footwear to the wearer's foot to reduce articulation of the bones of the mid-foot during use. An upper support may also be present. This is shaped and dimensioned to bear evenly against the front of the lower leg above the ankle joint. A complementary support may also bear against the lower leg at the rear and sides above the ankle joint. The support system allows proper flexion of the ankle joint while providing firm support for the bones of the mid-foot. When used in ski boots, the system gives the skier good balance and control of the boot even during fast downhill skiing.
