All-day warmth, built for real winter missions.
The Heat Sock 7.1 Toe Cap® was developed specifically for performance and race boots. Its particularly thin, shape-retaining knit construction enables direct power transfer in ski boots, making it our thinnest heated sock. The innovative Toe Cap® heating element warms the toes from above and below, allowing warmth to spread across the foot – without a battery, the sock wears like a premium ski sock.
Climate-regulating materials reliably wick away moisture, while the anatomical fit and reinforced ring band ensure a secure fit and high wearing comfort. The batteries are secured above the ski boot cuff, where they sit safely without getting in the way. Compatible with all Body Heat System batteries, the Heat Sock 7.1 Toe Cap® is the ideal choice for anyone who wants to feel full performance, comfort and precision even on the coldest ski days.
Compatible with all Lenz Body Heat System lithium packs (sold separately), the heat level can be adjusted directly on the pack or steplessly via the Lenz Heat App for precise control even under multiple layers.
