Socks and production method of same

Abstract

Improved sock or similar garment for preventing leg alignment problems is disclosed. The improved sock or similar garment has a structural region having an inelastic region woven together into a structure having a strong elastic intensity. When worn, the region forms a heel constricting band so as to join an area near a tip of the calcaneal tuberosity with a superior portion of the talus, wherein the heel constricting band divides the structure of the heel region in two.

Description

TECHNICAL FIELDThe present invention relates to a sock or a similar garment that is suitable for smoothly guiding the calcaneum in an anterior direction and the talus in a posterior direction and preventing abnormal abduction of the ankle joint, in order to prevent leg alignment problems or leg impairments caused by an osseous chain arising from abnormal movements in the ankle joint, with an aim to prevent, treat, or correct ankle joint impairments.BACKGROUND ARTConventionally, impairments of the lower body due to sports and other activities are said to arise from abnormal movements in which the ankle joint abducts, or in other words, a major axis of the foot is in a state of being oriented outwards with respect to an anterior-posterior axis of the tibia, when the foot undergoes dorsiflexion relative to the leg. This appears as an abnormal skeletal movement known as “knee-in toe-out” (i.e., the knee pointing inwards, and the toes pointing outwards; FIG. 1), and is regarded as a dyna...

AI Technical Summary

Benefits of technology

When the sock or a similar garment according to the first aspect is worn, a strong contracting force exerted by the heel constricting band pulls the calcaneum in an anterior direction, the talus and the calcaneum can be guided to an appropriate position, and an abnormal movement in the ankle joint can be corrected.

Also, in the sock or a similar garment according to the second aspect, a strong contracting force exerted by the upper heel constricting band and the lower heel constricting band makes it possible to prevent the heel constricting band from being displaced from an appropriate position joining the area near the tip of the calcaneal tuberosity with the superior portion of the talus during intense exercise or a similar situation.

Correcting the abnormal movement in the ankle joint as described above also resolves abnormal movement of the lower body induced by the osseous chain. As a result, body axis displacement, flat foot, pronated foot, supinated foot, O-leg (i.e., genu varum), X-leg (i.e., genu valgum), hallux valgus, and similar alignment problems; and waist pain, hip arthritis, shin splints, achilles tendonitis, plantar fasciitis, ankle sprain, and similar impairments, are resolved.

The method for manufacturing a sock or a similar garment according to the third and fourth aspects also makes it possible to readily form a complex configuration of the heel region of the sock or a similar garment according to the present invention using a circular knitting machine.

Problems solved by technology

This appears as an abnormal skeletal movement known as “knee-in toe-out” (i.e., the knee pointing inwards, and the toes pointing outwards; FIG. 1), and is regarded as a dynamic alignment problem.

Leaving the condition described above uncorrected causes a malignant circle of chronic pain, an increase in the recurrence rate of an impairment, a decrease in recovery capacity, joint deformation, and a decrease in competitive abilities, and results in an increase in the time required for improvement and recovery.
