Lenz Heat Sock 7.1 Thin

Race boots leave no room for bulk, and the Lenz Heat Sock 7.1 Toe Cap is Lenz's thinnest heated sock, built for performance boots. It's a slim, shape-holding ski sock with a heating element that warms the toes from above and below. Feet stay warm on the coldest days without losing feel in a tight boot.

Why we like it:

It skis like a premium thin race sock even without the battery, so it never feels like a compromise in a tight shell.

Features and Functions:

The Toe Cap heating element warms the toes from above and below, letting warmth spread across the foot. A thin, shape-retaining knit allows direct power transfer in ski boots, and a climate-regulating diamond knit moves moisture away. Anatomical knitting for left and right feet and a reinforced ring band keep it in place. The batteries sit above the ski boot cuff, out of the way. It's 89% polyester and 11% elastane, works with all Lenz Body Heat System batteries, and ships without batteries.

Bottom Line:

This is the heated sock for racers and expert skiers in tight performance boots who suffer cold toes. Pair it with a Lenz battery and stay warm all day.
