The new standard in durability and impact protection, the elite series heel saviors will double to triple the impact protection of stock insoles and increase impact protection to the max when placed under footprint insoles. Sloping from 6 mm to 2mm, the heel saviors will fit comfortable in any shoe. A highly resilent skin protects the inner foam for lasting durability and protection from blowouts. Expect these to last all year. Keep in mind these are sold in pairs!
