Proflex Heated Insole
ThermaCELL ProFLEX Heated Insoles are the latest innovation in cold weather comfort. With the same regulated heat as the Original, ProFLEX insoles include removable, rechargeable batteries so you no longer need to take out insoles to recharge. Simply swap out the battery packs to extend the heat as needed. To ensure your feet last as long as the warmth, the ProFLEX insoles are extra flexible and padded for all-day comfort
