Abstract
Abstract A ski boot for association with a ski, providing enhanced ski control, safety and comfort, comprising a lever element extending upwardly from a foot holder to the upper portion of the skier''s lower leg and operatively associated with said leg to restrict both lateral and longitudinal motion of said lever with respect to said lower leg, whereby motion of said lower leg during skiing is virtually completely transferred to the ski without immobilizing the ankle joint.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
152 words
A ski boot for association with a ski, providing enhanced ski control, safety and comfort, comprising a lever extending to the upper portion of the lower leg of a skier, a first means connected to the lower portion of said lever to hold the foot of said skier, a second means connected to the upper portion of said lever to engage the upper portion of said leg to restrict lateral motion of said lever with respect to said leg, a third means connected to the upper portion of said lever to engage the upper portion of said leg to restrict longitudinal motion of said lever with respect to said leg, and a fourth means whereby a ski may be firmly secured to said boot, characterized in that the portion of said leg between said first means and said second and third means is maintained substantially free of force-transmitting contact with structural elements.
Claim 2
Dependent Claim
