Therm-ic Battery Boot Heaters with Perform insoles

This system is easy to install but unlike the Classic insole which is flat, the Perform insoles have arch support and a heel cup for extra support for comfort. They also come in different shoe sizes. The heating elements are built into the toe area of the insoles. See our easy installation video.

If you have custom insoles, you need the Trim Fit system.

SuperMax - Uses rechargeable nickel metal hydride batteries and includes a global charger for use in North America or Europe.
