Regular Fit

Never freeze again with 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 fit in the calf area is ideal thanks to the increased elasticity. The socks are thus also perfectly suitable for stronger calves and thanks to the comfort cuff nothing slips. The knee-high heat sock 5.1 toe cap® has an integrated shin protector and 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 fibers dries quickly and efficiently wicks away moisture.

The rechargeable lithium pack can be attached to the sock cuff with snaps. The heat socks are compatible with all lithium packs of the Lenz Body Heat System.

The temperature can be conveniently controlled on your smartphone with the free Lenz heat app or directly on the lithium pack.

Slim Fit

The patented Toe Cap® heating element guarantees all-round warmth and heats the toes from above and below. The heat sock 5.0 toe cap slim fit knee socks are ideal for narrow feet and legs.

They are ergonomically knitted for an optimal fit and the ring bandage offers pleasant support on the foot. Shin protectors as well as further reinforcements at toe and heel prevent pressure points.

The skin-friendly material mix of merino wool and silk is breathable, fast-drying and comfortable to wear.

The lightweight rechargeable lithium pack battery is optional and sits barely noticeable under the special comfort cuff. The heat can be controlled directly on the lithium pack or also via the free Lenz heat app on your smartphone.
