Benefits & Features Due to the patented flexible and ultra-slim design with built-in EPITHELIUM®FLEX technology, the hallux valgus orthotic can easily be adapted to fit any shoe and it can be worn during the day, every day. Unlike a rigid hallux valgus splint, it acts during walking to address all of the factors that can aggravate the deformity The patented external tendon made from EPITHELIUM®FLEX silicone straightens the big toe. The extent of correction can easily be adjusted by exerting greater or lesser tension on the tendon. The EPITHELIUM®FLEX external tendon also absorbs pressure on the bunion and therefore relieves pain. The Epithelium® disc creates a comfortable toe piece that acts as a counter-support with the shoe and allows the 1st metatarsal to be pushed back. The extra-slim metatarsal compression sleeve acts against crushing and widening of the forefoot. Size Chart: Small : 4 - 5.5 Medium: 6 - 8 Large: 8.5 - 11
