Designed for expert skiers in extreme conditions, these thin, technical warming socks target cold extremities. Thermic developed this sock with a slim construction and Smart Elastic technology to maintain a perfect fit and feel inside the boot. The discreet, thin (2mm) SET heating line is integrated to diffuse subtle warmth around the toes without impacting fit. Polyamide fibers ensure a snug, supportive fit. Thermo-regulating knitting and Merino wool provide perfect insulation and breathability. Moiture-Vent Technology in the arch of the foot absorbs moisture and transports it outside via micro-channels, keeping the foot dry during exercise.
