Ski boot

Abstract

An alpine ski boot is provided that consists of a rigid sole and a shell-less substantially flexible upper portion that is attached to the sole. The boot is secured to the wearer's foot by laces or buckles. The boot is further secured to the wearer's mid-foot area by semi-rigid securing ears closed by a lever actuated ribbed nylon strap. The sole is comprised of rigid plastic and the heel and toe portions of the sole may conform to the requirements of ISO 5355 for ski boots. The ski boot has a plastic cuff that surrounds the upper portion of the ski boot that follows the movement of the lower leg and provides lateral support to the ankle while introducing minimal or no restriction to the fore and aft flexion of the ankle.

Description

technical field [0001] The present invention relates to a ski boot, in particular to a downhill ski boot, or an alpine ski boot, which has a safety-release binding. The invention also relates to ski boots that are difficult or impossible to do with plastic ski boots, more easily adapted to some alpine skiing techniques of the pre-plastic ski boot era. Background technique [0002] Before the advent of plastic ski boots in the mid-1960s, all alpine skiers used leather boots. To provide support, the leather on the lower part of the boot is several layers thick and quite stiff. New leather boots require a break-in period to soften the leather and improve the comfort of the boot. Leather boots are usually quite comfortable when run in. [0003] In addition to serving as a connection between the foot and the skis, leather ski boots fulfill two very important functions. First, the boot provides lateral support for the foot, ankle, and lower leg to allow the skier to adjust the...

AI Technical Summary

Problems solved by technology

In fact, the lateral support of leather ski boots is always less than that of plastic ski boots, thus providing the skier with less control in icy conditions and maintaining less control at high speeds

[0018] Another disadvantage of leather ski boots is that the soles of leather ski boots do not meet the requirements of "ISO5355, Alpine ski boots - Safety requirements and test methods". This international standard specifies the dimensions and allowable deviations of the soles of alpine ski boots. Adapts to modern ski bindings

[0019] Although one's alpine skiing technique should be a personal matter, it is actually constrained by the equipment available in the market
