Description

200300337 V. Description of the invention (l) ------ 1. Technical field to which the invention belongs The present invention relates generally to the wearing of feet, such as shoes, boots, boots: pads, and particularly to ski boots or snowboard boots The use of a rubber pad in front of and above one toe and a rubber pad in the back of the heel provide wearer comfort and protection. ~ 2. Prior art Anyone skiing or snowboarding has felt the pain of squeezing his toes and heels against the inside of the boots. The boots described below provide a solution. / Moon Valley Board and Skier: Usually made by combining a track pad and a shell. Although boot liners can be made from different layers of foam, they are not sufficient to absorb impact to alleviate the problem. The foam of the pad is typically soft so that the impact absorbency it provides is insufficient. Basically, a skier's toes hit the shell with only a layer of fully compressed foam in between, which is painful and can cause injury.

Kunesh, a two-layer inflatable sock, U.S. Patent 5,596,77, (January 28, 1997), mentions the placement of an adjustable inflatable bladder that is partially filled with a plastic solution or hydrogel inside a sock to increase Comfort and reduce blisters. However, the socks that Kunesh mentions are too soft for a ski boot. To control the skier: Or the snowboard wearer transfers power to the snowshoe or snowboard. Kunesh's socks make ski boots or snowboards difficult to control because it provides too much cushion; basically, the additional cushion weakens the control exerted by the wearer.

Page 4 200300337 V. Description of the Invention (2) — 6, 082, 027 (July 4, 2000), referring to the use of a separable and attachable foam insert to adjust the internal size of a boot. Waghunhurst seeks the same solution: adapting the child to different foot sizes. Because Wagonhurst teaches foam inserts to accommodate different foot sizes, the inserts are designed to be compressible. The compressible pad becomes compressed in a high impact environment and is insufficient to protect the wearer's toes. Third, the content of the invention

The boots described below alleviate the risk of injury and pain when wearing skis or boots. A soft rubber pad made of styrene butadiene rubber (SBR) or similar elastic material is placed between the foam and the fabric layer forming the toe a to provide substantial protection to the wearer's toes from impact without reduction Comfort or function. To provide maximum protection the pad covers the entire front and top of the toe box. The pad can fit between the foam layer of the toe box or anywhere between the inside of the boot pad and the inside of the outer fabric, and the glue further holds the pad in the cavity. The rubber pad does not extend into the upper of the boot or the moon, so when it is necessary to control a snow boot or a snowboard bound to the boot, it has no negative effect on transferring the force from the user's foot to the shoe. Similarly, a rubber pad is inserted into the boot pad in the heel block to provide protection for the wearer's heel from being impacted by the heel block of the boot, while the rubber pad inside the heel does not extend or extend upward into the The ankle or arch area is shifted with the power required for ski boots or snowboards.
