Never freeze again with the patented Toe Cap® technology. The flat, sewn-in heating element is not bulky and provides all-round warmth for the toes - for up to 14 hours.

The knee-high heat sock 5.0 toe cap® has an integrated shin protector as well as protectors in the toe and heel area. Thanks to the ring bandage, the socks do not slip on the foot.

The sophisticated material mix of merino wool, silk and functional fibres dries quickly and efficiently wicks away moisture.

The rechargeable lithium pack is attached to the sock cuff with press studs. The temperature can be conveniently controlled on your smartphone with the free Lenz heat app or directly on the lithium pack.
