Combines the exclusive "Ankle Lok" lacing system with non-stretch nylon figure-eight straps. The straps simulate a professional taping procedure and help lock the ankle in a protected position. The seamless arch fits the contour of the foot and helps avoid irritation to the bottom of the foot. The full elastic back ensures unrestricted blood flow to the achilles tendon and virtually eliminates the chance for blistering. Ballistic nylon construction is thin and lightweight, yet very durable.
