The Lenz 5.0 Toe Cap socks are made from a fabric that blends polyester, polyamide, merino wool, silk, elastane and polypropylene. The merino wool and silk contribute to their ability to keep your feet warm. They are reinforced in the most sensitive areas. The integrated heating elements are almost imperceptible and allow to spread a soft and homogeneous warmth, especially on the toes.
These heated socks are sold with 2 rechargeable lithium rcB 1200 batteries that have a life of up to 14 hours, but also with cable and USB charger. Thanks to the Bluetooth system, it is possible to manage the level of heating directly from your smartphone.
