The present invention relates to an auxiliary shoe, and more particularly, to a new auxiliary shoe for treating metatarsal adduction, in which the forefoot of the auxiliary shoe can be rotated according to the degree of flexion of the user's foot.

Metatarsal adduction is a foot deformity commonly found in infancy, in which the outer shape of the foot is bent in a “C” shape. In the case of a normal person, when viewed from the plantar side, the line dividing the heel crosses the second toe or passes through the webbing space between the second and third toes. However, in patients with metatarsal adduction, the line dividing the heel is located on the third toe or outside it, and the more outside it is, the more severe metatarsal adduction can be seen.

Metatarsal adduction may be corrected spontaneously if the degree is not severe. However, if the degree is severe, it is necessary to continuously stretch the foot or perform plaster correction for about 6-12 weeks. After correction is obtained through plaster correction, auxiliary shoes are worn for 23 hours a day for 3 months to prevent the recurrence of deformation.
