The sewn-in heating element in the heat sock 4.0 toe cap® provides warmth and keeps the feet warm. The toes are warmed from both above and below. The socks are knitted left/right and promise a perfect fit thanks to the ring bandage. Padded reinforcements protect 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 in place. It is operated either at the touch of a button on the lithium pack or with the free smartphone app.
