  • About Lenz

The sewn-in heating element in the heat sock 4.1 toe cap provides warmth and keeps the feet warm. The toes are warmed both from above and below. 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 socks are knitted left/right and promise a perfect fit thanks to the ring bandage. Padded reinforcements protect the toes and heel. Natural merino wool combined with technical fibers absorbs moisture and keeps warm.

The comfort cuff with snaps fixes the lithium pack. This can be purchased as an option to the heat socks. It is operated either at the touch of a button on the lithium pack or with the free smartphone app.

The Lenz Body heat system warms the body from head to toe. The lithium pack rcB 1800 can be used for all models of the Lenz heated socks, heated vest, heated bandage, heated gloves, heated pants and the LED system.

The lithium packs are connected with push buttons. The lithium packs are small, light and provide up to 20 hours of heat at the touch of a button for work, sports and leisure.

This increases the ability to perform and concentrate, even in cold temperatures, and ensures that blood circulation is maintained.

The lithium packs rcB 1800 can be controlled directly on the lithium pack. With the Lenz heat app, however, the heat can also be regulated continuously via smartphone. Optimal when the lithium packs are under several layers of clothing.
