Warm feet at last. The integrated heating element in these socks wraps your feet and toes with electric warmth and are great for super-cold conditions when you're sitting still or for crawling into a cold sleeping bag at night. The 2 battery packs (one for each foot) are rechargeable. The temperature settings can also be controlled from the battery or via your Bluetooth-equipped smart phone. This slim fit version is ideal for narrower feet.
- Socks are made of thick blend of synthetics and merino wool that provides good moisture wicking.
- Ergonomic knitting for a soft toe seam, strategic padding on the shins and a great fit.
- Integrated heating element completely wraps around both the top and bottom of the toes as well as the forefoot for the ultimate in cozy warmth.
- Lightweight lithium-ion battery packs attach with press studs to the cuffs, where they are out of the way of boot tops.
- Temperature settings: 42°C (battery life 10-14h), 52°C (5.5-7.5h) and 60°C (3.5-4.5h). The sock buffers these temperatures and prevents direct contact with skin.
- Settings can be adjusted on the battery pack or remotely via Bluetooth 4.0. (Requires Lenz Heat app).
- Remaining charge is visible on the battery packs or the Lenz Heat app.
- Includes a 100-240V AC wall charger with charge indicator.
- Unisex sizes are designed to fit narrower feet: Small fits Euro 35-38, Medium fits Euro 39-41, Large fits 42-44.
- Replacement socks are available.
Layers of cushioning, in some athletic socks, are knit in to reduce impact. Mapped socks are activity-specific and will offer cushioning in common pressure areas.
Left foot and right foot specific socks provide precise fit.
