Therm-IC Ski Boot Heaters

How to select your battery boot heating system!

First, select a heating system! A heating system is batteries and heating elements. You have 4 options.

Batteries only - If you have a pre-installed heating elements in your boots, (you'll know this by the wires coming out of your boots) all you need are the batteries and charger.
Batteries with TrimFit system - If you do not have pre-installed heating elements and have custom insoles or very close fitting boots, this is the best way to heat your boots.
Batteries with Classic insoles - This is our most popular system! If you do not have pre-installed heating elements or custom insoles, this is the easiest system to install! The Classic insoles have the heating elements preinstalled at the toes. All you do is trim to size and install.
Batteries with Perform insoles - If you do not have pre-installed heating elements or custom insoles, this is easy to install and the Perform insoles offer extra support for comfort. The heating elements are pre-installed in the insoles at the toes.
