AI Technical Summary

Technical Problem

Existing diabetic socks and orthotic insoles fail to effectively distribute weight-bearing load on bony prominences such as toe tips, metatarsal heads, and heels, leading to ulcer formation, infection, and potential amputation, and do not protect against injuries from hard objects when walking barefoot indoors.

Method used

A sock design featuring a cushioning material centered on the sole, rising from the toes to the heels with chamfered corners, physically supporting the foot arch and distributing load, combined with pile-knitted toe and heel sections and a ribbed knit opening, to prevent ulcer formation and floor injuries.

Benefits of technology

The sock effectively prevents ulcer formation and reduces sole injuries by supporting the foot arch and distributing load, allowing safe barefoot indoor activities while protecting against hard objects.

Abstract

By simply wearing these socks, diabetic patients can effectively prevent ulcer formation while going about their daily lives indoors. This is achieved by physically supporting the arch of the foot, distributing the load on bony prominences such as the toes, metatarsal heads, and heels. [Solution] This sock 100 for diabetic patients is composed of a foot portion F that covers from the toes to the heel, including the instep and sole of the foot, and a leg portion L that extends from the foot portion F and covers from the ankle to at most below the knee. A large cushioning material 124 is provided on the inner surface of the foot portion F, approximately in the center of the sole of the foot, with a width approximately equal to the width of the foot portion F and a length of 1 / 2 to 2 / 3 of the length of the foot portion F. The cushioning material 124 physically supports the arch of the foot, thereby distributing the load on bony prominences such as the toes, metatarsal heads, and heels, and thus preventing ulcer formation.
