Thermic Flat Heat Insole

The Thermic Flat Heat Insole is an exceptionally thin heated insole that will elevate your comfort and keep you warm in the cold weather. The Flat Heat Insoles can be trimmed with scissors to fit any size shoe or ski boot; always follow the trim lines on the bottom to avoid cutting the heating element in the toe area. The heating element is only compatible with Thermic C-Pack Batteries (not included).
