The Therm-ic Sole Perform insoles are heated footbeds designed to bring warmth to your ski boots by using Lenz battery packs. Developed with the needs of winter sports in mind, these insoles slot directly into your existing ski footwear, keeping your toes toasty when temperatures drop on the slopes.
Made by Therm-ic for compatibility with Lenz systems, the Sole Perform combines low-profile heating elements with a cushioned base, so you won’t sacrifice comfort or fit. By distributing gentle heat evenly underfoot, they help maintain circulation and reduce the chill that can slow you down on longer tours or all-day runs.
