5.1 Heat Sock delivers targeted warmth for long, cold ski days
What Our Gearhead® Experts Are Saying:
"I’ve tried every trick to keep my toes warm, but the Lenz 5.1 Heat Sock is the real deal. The heat zones wrap around the entire toe box so your feet stay warm—not hot spots, just even comfort all day. I pair mine with the Lenz lithium packs and control the temperature through the app. Once you ski with them, you’ll never go back to cold feet again."
When icy chairlifts and midwinter temps threaten our focus, the Lenz 5.1 Heat Sock keeps our feet comfortable from first run to après. Designed for high-performance warmth, these heated socks feature an integrated 360° heating element that surrounds the toe box, creating a consistent layer of heat where we need it most. The Toe Cap technology ensures complete coverage around the front of the foot, preventing cold spots on even the most frigid days.
Built from a technical merino wool blend, the 5.1 Heat Sock wicks away moisture while offering natural odor resistance and soft, breathable comfort. The anatomical knit provides a snug, performance-oriented fit that stays secure in ski and snowboard boots without adding unnecessary bulk. Pair them with Lenz’s rechargeable lithium battery packs and the Lenz Heat app for up to 14 hours of adjustable, app-controlled warmth—perfect for dawn patrol tours, cold lift rides, or snowshoe missions.
