The purpose of a bunion sports belt is to correct mild bunion deformities. The belt focuses on maintaining the normal shape of the joint and relieving pain in the metatarsophalangeal joint. Bunions are usually caused by wearing pointed shoes, high heels or having genetic factors. For mild bunions, they can be corrected with braces, athletic bands, straps, and corrective insoles, which usually achieve very satisfactory results. For moderate to severe bunion deformity, surgery is required. Surgery is mainly to release the contracture of the calcaneus muscle, tighten the joint capsule, remove the local calcaneal bursitis, tighten the joint, and bring the joint to a normal physiological state.
