Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock with improved fit and support between shoes and feet.

[0002]

2. Description of the Related Art In sports where the movement of the legs is intense,
Support to prevent slippage between the shoe and foot and fit to reduce fatigue are important. As a method for enhancing the fit, for example, in Sho 55-132701, the ankle part, the back part of the foot and the lower part of the foot are thickly formed, and the heel part, the bottom part and the back part of the foot and foot are formed thinly, and the thick part is pile knitted. Discloses a sock whose thin portion is formed by flat knitting.

Further, Japanese Patent Laid-Open No. 60-162801 discloses a sock in which the portion extending from the tip of the foot to the bottom, and further extending from the heel to both the inner and outer sides to the back of the foot is made of thick pile knitting. Further, in Registered Utility Model No. 3058783, socks are disclosed in which a sole portion is formed into a pattern knitting structure structure having an uneven pattern in order to make the sock adhere to the sole of the foot.

[0004]

[Problems to be Solved by the Invention]
The conventional example disclosed in -132701 is primarily intended for ski boots made of synthetic resin,
The purpose is to reduce the impact on the foot by thickening the socks at the ankle / dorsal area where the boot touches the foot and the portion corresponding to the lower toes where weight is applied. Therefore, the thicker the sock for ski boots is, the more the shock is alleviated, but the sock becomes a sliding material, and the supportability of the foot and the boot is rather deteriorated.

The conventional example disclosed in Sho 60-162801 is to improve the fit by pressing the foot against the shoe at the tip of the foot and the heel. It is not possible to prevent the displacement of the foot in the shoe due to the change in the arch part of the foot. Therefore, there is a problem that the back of the foot is worn away.

Further, registered utility model No. 3058783 is
It was designed to prevent the socks from slipping off.With such a structure, slippage between the socks and the sole of the foot can be prevented, but when the shoes are deformed during exercise or the foot arch changes due to weight shift. It is not possible to prevent the displacement of the foot in the shoe. Moreover, since the space of the arch varies from person to person, it is necessary to change the size and thickness of the unevenness depending on the wearer.

Therefore, there has been a demand for socks that can improve the supportability without impairing the fitting property between the foot and the shoe. Therefore, we conducted a biomechanical analysis to study the movement of the bones of the foot.By restraining the metatarsophalangeal joint, it is possible to prevent the foot from slipping forward. It has been found that it is possible to prevent changes in the arches of the feet due to movement.

[0008]

In view of the above points, the sock of the present invention has the following structure in order to restrain the metatarsophalangeal joint and the scaphoid. That is, the sock is characterized by having a restraining portion having a pile tissue provided on the dorsal side of the foot from the metatarsophalangeal joint to the scaphoid so as to have a thickness. By thickening this part, the surface pressure applied to the scaphoid from the metatarsophalangeal joint can be made larger when wearing shoes than other parts, and the feet can be kept inside the shoes even when making a hard movement. It is possible to prevent displacement in the toe direction or the twisting direction.

Further, the restraint portion is a dorsum side of a band-shaped portion having a width of 10 mm or more and 40 mm or less from the metatarsophalangeal joint toward the heel side, and / or a lateral tarsal joint including at least a scaphoid. Width 10mm or more 40m covering the space between the tarsal metatarsal joint
Socks that are the dorsal part of the foot in the strip-shaped part of m or less.
In order to prevent slippage of the foot in the shoe, it is sufficient to restrain only the part from the metatarsophalangeal joint to the heel side and the vicinity of the scaphoid. It is not necessary to thicken the part from the vicinity of the center to the proximal end of the metatarsal bone.

Therefore, only the portion from the metatarsophalangeal joint to the heel side and the vicinity of the scaphoid are thickened by using the pile tissue, and the other portions are thinned, thereby shortening the manufacturing time and reducing the cost. At the same time, it is possible to secure air permeability and prevent stuffiness in the shoes by configuring the thin portion with a mesh, for example.

Furthermore, the sock is characterized in that a twisted design yarn is used on the surface of the restraint portion. By providing the surface of the restraint portion, which receives a high pressure from the shoes, with irregularities on the surface such as a design twisted yarn, it is possible to prevent the gap between the socks and the shoes.

Further, the whole or at least a part from the metatarsophalangeal joint to the scaphoid is 156 dtex or more and 470 or more.
A high-tensile polyurethane yarn having a dtex or less is knitted so as to be continuously knitted from the back of the foot to the side of the foot. The high-strength polyurethane thread tightens the foot when worn, so that the slip between the foot and the sock can be prevented.
