<p>The ski-boot consists of a shell (1) forming the upper and sole, a collar (4) which fits around the base of the leg and a second collar (7) which supports the inside of the leg. The second collar is semi-rigid and is attached to the first collar, covering slightly more than half of the circumference at the top of the boot. A wedge-shaped projection (12) fits into a notch (13) at the top of the boot and controls the flexibility of the boot when the leg is flexed.</p> |
