Therm-ic Ultra Warm Nordic Socks S.E.T® -calfskin, 39-41 (T45-3100-003_03)

Tackle the coldest weather conditions with these thin, technical cross-country ski socks designed specifically for Nordic skiers in very cold climates. Thanks to their thin construction and Smart Elastic Technology®, these socks won't alter the fit of your boots, providing optimal comfort and precise sensations during your workout.

The discreetly integrated, thin S.E.T® heat line (2 mm) distributes subtle heat around the toes without affecting the fit of the sock in the shoe. Polyamide fibres that wrap around the foot and shin ensure a snug fit and support during training, guaranteeing stability and comfort throughout the outing.

Merino wool socks 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 it feels wet, ensuring your feet stay dry and warm, even during strenuous activity. The knee-length height also provides extra comfort, covering your foot completely and offering extra protection from the cold.
