Description

  The present invention relates to a mountaineering shoe. In particular, the present invention relates to a mountain climbing shoe for alpine use. The following description applies without loss of generality.

  As is well known, mountaineering shoes have leather and / or synthetic fibers that are designed to accommodate feet and ankles up to the user's calf. It is placed along a thermally insulated material, made of rubber or non-slip material with the desired depth, and stitched and / or glued to completely cover the back of the user's foot And has a sole attached so as not to move to the bottom of the bump.

  Alpine climbing shoes have an outer gaiter made of waterproof material. It is usually sutured and / or glued directly to the periphery of the sole. It is formed to substantially cover the outer surface of the bump to the top of the shoe. It tightens the user's calf over the top edge of the shoe.

  The outer gaiters are substantially flush with the vertical center plane of the shoe, from the toe area of the upper to the top of the gaiters, so that the user can easily wear them and tighten the shoes. It has a waterproof zipper that extends along the front.

  Unfortunately, since the waterproof zipper is placed in front of the bump, when walking, a part of the zipper placed on the ankle is repeatedly bent and stretched for a long time. This causes structural damage to the zipper. As a result, water penetrates into the shoe and various problems occur.

  In fact, mountaineering equipment is often used to work in air so cold that the water freezes within seconds even inside the shoe. Also, the ice formed inside the shoe causes the user's feet to be hypothermic and / or frostbite.

  To solve this problem, some alpine climbing shoe manufacturers extend along the gaiters that follow the curve that continues along the outside of the bump, starting at the toes of the upper to the torso, that is, to the level of the talus. Finally, we decided to use a waterproof zipper that bends in the direction of the top of the gaiters. The zipper remains substantially parallel to the vertical axis of the shoe cylinder, i.e., parallel to the tibia.

  However, this waterproof zipper configuration is very cumbersome when putting on and tightening shoes, as it is difficult for the user to grip some of the bumps when the gaiters are open.

  In addition, the waterproof zipper makes it difficult for the slider to move along the portion of the ankle where the radius of curvature of the zipper is small. Therefore, local abnormal meshing occurs in the zipper body.

  Local anomalous engagement breaks the zipper connection in a short time and causes many problems associated therewith.

  An object of the present invention is to provide a mountain climbing shoe that prevents abnormal engagement of a waterproof zipper of an outer gait, which is easy to put on and fasten the shoe.

  In order to solve the above object, a mountain climbing shoe according to claim 1 is provided according to the present invention. As a preferred embodiment, a mountaineering shoe according to any claim dependent on claim 1 is provided.

  In one aspect of the invention, the present invention provides mountaineering shoes. The mountaineering shoes are fixed to a part of the lower side of the bump so as to cover the back side of the user's foot and a bump shaped to accommodate the user's foot and ankle substantially up to the calf height. The sole and the outer sock-shaped gaiters that completely cover the bumps while squeezing the outer surface of the bumps up to the top of the bump shoe shell, and the user reaching the bumps placed underneath the gaiters And a zipper that extends along the gaiters so that it can be opened. The zipper extends along the gait according to a substantially helically curved path starting near the front of the gaiter and ending at the upper opening of the gaiter's shoe, and at the end of the stretch, the axis A of the shoe Characterized by having a substantially spiral trajectory around.
