Sock

Abstract

A sock 1 according to the invention is provided with an outer low-elasticity portion 7 having a length extending from a region near a base part of a fifth toe to a region near an outer malleolus part 3a via an outer face, and a width extending from a region near a first toe side of a fourth toe on an instep side to a region near a first toe side of the fifth toe on a volar side, an upper taping low-elasticity portion 8 formed in a direction substantially toward an inner malleolus part 3b side from a portion between the ankle and the region near the first toe side of the fourth toe in the outer low-elasticity portion 7 on the instep side, and an upper ankle low-elasticity portion 10 formed in the upper ankle part in a circumferential direction.

Description

BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates to a sock capable of sufficiently reducing the load on the foot and improving movement capability by everting the ankle.[0003]Description of the Related Art[0004]A sock that everts the ankle is conventionally known. In a sock of this kind, a band-shaped first low-elasticity region 101 that is less elastic than other regions is provided in an instep part. The first low-elasticity region 101 includes at least the ankle flexion portion 101d, and extends on the lower end side of the ankle flexion portion 101d to the base part of the toe, with the center line (thereof) relative to the width in a course direction gradually shifting to the fifth toe side. A lower end portion 101b is located in an area from the base part of the third toe to the base part of the fifth toe (see FIG. 3). A side portion 101c on the fifth toe side close to the lower end of the first low-elasticity region extends to the sol...

AI Technical Summary

Benefits of technology

The present invention provides a sock that can reduce the load on the foot and improve movement capability. The sock has an arcuate shape, with the instep side of the outer low-elasticity portion having a width extending to the region near the first toe side of the fourth toe. This creates a force in an everting direction while tightening the entire foot on the outer side of the foot portion. This force pulls the entire bottom of the foot towards the inner malleolus part, making it stable when landing. The lower taping low-elasticity portion pulls the entire foot in the direction stable with the inner malleolus part, while the upper taping low-elasticity portion pulls the entire bottom of the foot in the opposite direction. This ensures that the entire bottom of the foot is made parallel with the ground when walking or running. The sock is securely fixed at the ankle position, easy to put on and take off, and avoids an oppressive sensation or deterioration of blood circulation.

Problems solved by technology

However, because the conventional sock, which effectively prevents inversion sprains by applying a force pulling up the entire fifth toe side of the foot, lifts up the foot from the fifth toe side in the direction toward the ankle flexion portion, this sock cannot sufficiently turn the entire foot in the everting direction.

Therefore, during walking, the outside of the bottom of the foot lands before the inside after the heel lands, and the conventional sock does not allow the inside and outside of the foot to land on the ground substantially simultaneously.

Since the conventional sock thus does not allow the inside and outside of the bottom of the foot to land on the ground substantially simultaneously during walking, a problem arises in that the load on the foot cannot be reduced sufficiently.

However, the conventional sock also does not allow the inside and outside of the region near the toe tip part of the bottom of the foot to land on the ground substantially simultaneously during running.

Thus, during running, especially during short-distance running, given that the sock does not allow the inside and outside of the toe tip part of the bottom of the foot to land on the ground substantially simultaneously, a problem arises in that time is required for the temporal difference that occurs between when the inside and the outside of the region near the toe tip part of the bottom of the foot land on the ground, and the person who wears this sock cannot do a fast time for that reason.

Furthermore, especially during short-distance running, if the outside of the foot lands and then the inside of the foot lands, the running direction points outward of the foot during running, and therefore, a problem also arises in that the person who wears the sock unconsciously runs in a direction that slightly deviates from a straight direction, and cannot do a fast time for that reason.
