Abstract
Abstract A ski boot has a rigid base shell which is adapted to surround the foot of a skier and an upper adapted to surround the bottom of the leg of the skier. The upper is journalled along a first axis on said shell base and comprises at least two portions, one of which is in the form of a distribution plate journalled to the front cuff portion of the upper along a second, distinct axis. The distribution plate distributes the contact pressure which is normally created between the leg of the skier and the front upper edge of the cuff over a front upper zone of the cuff to enhance the comfort of the skier. The distribution plate helps to compensate for the difference in the angle of movement of the leg of a skier and of the upper when the skier exerts a forward flexion force while skiing.
