Lenz Heat Sock 7.1 Toe Cap is the thinnest heated sock from Lenz, developed for performance and race boots with low-profile Toe Cap heat.

Complete set: Lenz Heat Sock 7.1 Toe Cap + Lithium Pack rcB 2000 batteries + charger

The Heat Sock 7.1 Toe Cap was developed specifically for performance and race boots. Its particularly thin, shape-retaining knit construction supports direct power transfer in ski boots, making it the thinnest heated sock from Lenz. The innovative Toe Cap heating element warms the toes from above and below so warmth can spread across the foot.

Climate-regulating materials wick moisture away from the skin, while the anatomical left and right fit and reinforced ring band help keep the sock secure and comfortable. The batteries sit above the ski boot cuff, where they are securely fixed and do not get in the way. Without a battery, the sock can also be worn as a high-quality ski sock.

The included rechargeable Lithium Pack rcB 2000 batteries are part of the Lenz Body Heat System and provide up to 23 hours of heat for socks on the low setting. Heat can be controlled directly from the battery or through the Lenz heat app on your Smartphone.
