HEAT 4.1 Socks
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 therefore also perfect for stronger calves and nothing slips thanks to the comfort cuff.
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 fibres absorbs moisture and keeps you warm.
The comfort cuff with press studs fixes the lithium pack. This can be purchased as an option with the heat socks. It is operated either at the touch of a button on the lithium pack or with the free smartphone app.
