Spenco Medical introduces the PolySorb ProForm, an insole that provides cushion and support for tight-fitting shoes. The ProForm, an ultra-thin insert, is designed to provide comfort in shoe styles that typically do not have room for an insole. Its four-way stretch top cloth helps prevent blisters and is treated with an antimicrobial to control odors. The insole provides targeted cushioning and shock absorption in the forefoot and heel, with a deep heel cup with a SpenCore Heel Plug for extra cushioning and a contoured arch support in soft polyurethane foam. It retails for $19.99 per pair.
