The peroneal tendons, longus and brevis, run behind the lateral malleoli on the outside of the ankle. Either injury or overuse can weaken or damage these tendons, leading to pain and swelling on the outside of the foot and ankle. BioSkin Foot and Ankle Braces are designed to alleviate pain and speed recovery from peroneal injuries. Supportive straps mimic the function of the peroneals, allowing them time to heal, while medical-grade compression provides pain relief and enhanced proprioception.
