Therm-ic battery boot heating systems are designed to combat sub-zero temperatures and ensures that your winter sport experience is enjoyable. The Therm-ic Perform insoles are easy to use, easy to install and suitable for any boot and shoes. The Therm-ic SmartPack 1200 with Remote Control and Perform insoles is designed to work in any boot or shoe. The SmartPack 1200 with Remote Control is unique because it uses Lithium-ion batteries which are lighter in weight than AA or nickel metal hydride batteries. Lithium-ion batteries weigh almost half of what the other system batteries weigh and are smaller in size.
