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.
A ski boot having a rigid shell base adapted to surround the foot of the skier and an upper adapted to surround the bottom of the leg of the skier, wherein said upper comprises a front cuff, wherein said front cuff is journaled along a first axis on said shell base, wherein said upper further comprises means for distributing the contact pressure between the leg and the front upper edge of the upper over a front upper zone of said upper, wherein said distribution means comprises a pressure distribution plate which is journaled about at least one additional axis located on said front cuff at said front upper zone.
A ski boot having a rigid shell base adapted to surround the foot of a skier and an upper adapted to surround the bottom of the leg of the skier, wherein said upper comprises a front cuff, wherein said front cuff is journalled along a first axis on said shell base, wherein said upper further comprises means for distributing the contact pressure between the leg and the front upper edge of said upper over a front upper zone of said upper, wherein said first axis is misaligned with a journal axis of said leg of said skier around which said leg of said skier is adapted to pivot during forward flexion, wherein for a given forward flexion of said leg, said leg pivots forward to a greater extent than said front cuff, wherein said distribution means further comprises means for compensating for said misalignment of said journal axis of said front cuff and said journal axis of said leg so that said front upper zone of said upper flexes forward to substantially the same degree as said leg during forward flexion of said leg.
