Ski boot and ski boot-binding

摘要

A ski boot and a ski boot incorporating a releasable ski binding which attaches the boot to a ski. The boot-binding includes a first connecting portion secured to the ski, a second connecting portion secured to the boot, a plunger combination for releasably coupling the first and second connecting portions so that the boot may release in any direction, and an actuation device engaging the plunger combination for maintaining coupling of the first and second coupling portions. The actuation device has a pivotal lever arm mounted for withdrawing one of the plungers and an arm stay secured to the ski boot for releasably retaining the pivotal lever arm. The ski boot includes a living hinge in the sole to facilitate walking in the boot, and the hinge may be locked to inhibit the hinging function. The boot extends well above the ankle and is stiffened on the inside or outside to securely mount the arm stay. For retaining a foot in place, the boot includes a foot-enveloping foot positioning device which surrounds the arch and instep of a foot inside the ski boot when the boot is worn. The foot positioning device is adjustable to both fit the foot and also hold the foot at the heel of the boot.
