Thin, precise ski socks designed for athletes in extreme conditions. Their thin construction, combined with Smart.Elastic. technology, allows for an unaltered fit in the boots for maximum comfort and feel. The thin (2mm) S.E.T heating line is discreetly integrated into the sock to diffuse subtle warmth around the toes, without impacting on the fit of the sock in the shoe. In addition, the polyamide fibres, which provide tension around the foot and leg, ensure that the sock fits snugly and supports the foot during exercise. Made from merino wool, these socks offer excellent insulation and moisture management. Merino wool regulates temperature and humidity, is breathable and insulating. It is able to absorb up to 33% of its own weight in moisture before it appears wet. This fibre therefore keeps your skin dry and warm. It acts as an insulating layer offering optimal thermal insulation. Thin heating element: The thin (2mm) S.E.T heating line is discreetly integrated into the sock to diffuse subtle warmth around the toes without impacting the fit of the sock in the shoe. Precision: 3 factors ensure the precision of the socks in skiing: sock knitting, thickness and tension. These socks are knitted with 200 needles and are fully engineered with an inside-out construction (no yarn cut into the socks), one of the highest definitions available for socks, the tension is strong but inclusive to keep the sock around the feet and legs and the thickness is low to improve contact with the ski boot. Warmth: Thanks to the merino wool, the socks provide warmth and wick away moisture. Features: Made from merino wool, these socks offer excellent insulation and moisture management.
