The Heat Socks 5.1 in slim-fit design (also available in kids' sizes) fit snugly around narrow feet and legs for optimal heat transfer to the toes. The premium merino-silk blend provides a soft, comfortable feel, while reinforced padding at the most stressed areas reduces pressure and prevents fatigue. The socks stay securely in place without slipping, allowing you to fully focus on fast descents and challenging tours.

The Lithium Packs rcB 1200 keep your feet comfortably warm for up to 14 hours and remain securely attached to the sock cuff without getting in the way. Heat can be adjusted directly on the battery in three levels or continuously via the Lenz Heat App on your smartphone. The interval function allows finer control of heat, so you can maintain the perfect warmth at every run, every altitude, and every break – for maximum performance and comfort throughout your ski day.
