CURREX ActivePro Insoles are a full-length, semi-rigid orthotic arch support insole that is designed specifically for your arch type. They support the foot dynamically in order to prevent over-stress situations and also to strengthen the foot muscles and tendons at the same time for those with excessive pronation or supination. They feature a DryTek top cover that helps wick moisture away, Freeflex, a mid-level memory foam that is constructed with bamboo charcoal to reduce foot odor, CurEVA, an EVA foam rubber compound that is designed to mold to your heel and reduce excess motion within your shoes, and a poron heel and metatarsal pad that helps provide additional cushion from impact and shock absorption.
