Hallux valgus prevention and correction shoe

Technical Field

The invention relates to the technical field of foot health care, in particular to hallux valgus prevention and correction shoes.

Background

Hallux valgus deformity refers to the lateral deflection of the big toe at the first metatarsophalangeal joint. Hallux valgus is a complex anatomical deformity and is therapeutically very challenging. The hallux valgus refers to the prominent medial protrusion that occurs in hallux valgus deformity, but in general the terms are used interchangeably. Hallux valgus is the most common lesion affecting the hallux, most often seen in middle-aged and elderly women, most often occurring in people with genetic predisposition and long-term wearing of unsuitable shoes which exert abnormal pressure on the hallux. The stiffness of the thumb is generally characterized in that the big toe deflects outwards at the first metatarsophalangeal joint, obvious osteophytes appear at the inner side of the joint, and the soft tissue at the osteophyte of some patients is red and swollen and has effusion due to long-term friction and extrusion of shoes, which is called bunions. Patients with severe hallux valgus may experience other toe deflections, straddling. Patients with hallux valgus do not always have pain and deformities are not proportional to pain. The main cause of pain is acute bunions caused by pressure and friction after the inner side of the metatarsal head bulges. The hallux metatarsophalangeal joint is long-term abnormal, and osteoarthritis causes pain and callus under the 2 nd to 3 rd metatarsal heads causes pain.

The shoe is composed of a sole and a vamp, the sole surface is generally taken as an interface, the following parts are collectively called the sole, a heel is attached to the sole and is one part of the sole, and the sole can be made of multiple layers of materials; the vamp is generally called as the vamp above the interface, the vamp can be formed by splicing a plurality of surfaces, the small area of the small vamp is seen as a line which does not form a surface, but the vamp is also a vamp, and accessories such as shoelaces and the like can be arranged on the vamp and belong to one part of the vamp.
