Face the coldest weather conditions with these thin, technical cross-country skiing socks, designed specifically for Nordic skiers in extremely cold climates. Thanks to their thin structure and Smart Elastic Technology®, these socks do not alter the fit of your shoes, providing optimal comfort and precise sensations during training.

The discreetly integrated, thin S.E.T® heating line (2 mm) spreads subtle warmth around the toes without affecting the fit of the sock in the shoe. The polyamide fibers that wrap around the foot and calf ensure a good fit and support during training, guaranteeing stability and comfort throughout your journey.

Socks made from merino wool offer exceptional thermal insulation and moisture management. Merino wool is known for its ability to regulate temperature and moisture while remaining breathable. It can absorb up to 33% of its own weight in moisture before feeling wet, ensuring that your feet stay dry and warm, even during strenuous activities. The knee-length height also provides added comfort, fully covering the foot and offering extra protection from the cold.
