Starter packs include a trim-to-fit pair of reusable insoles and 2 pairs of ELOS Heat Packs, all in one box. Perfect for any outdoor endeavor this winter!

The trim-to-fit design works in running shoes, hiking boots, ski boots, work boots, and most everyday footwear. For best performance, use them in enclosed footwear to keep heat contained.

The insole shell is fully reusable. Only the heat packs are single-use. Swap in a fresh pack whenever you need heat again.
