SIDAS Ski Race S.E.T Heated Ski Socks, Size: 39-40

The thin, heated Ski Race S.E.T socks are engineered for ski athletes pushing their limits in extreme conditions. With a slim, technical profile, they deliver optimal comfort, precise boot feel, and subtle, targeted warmth without compromising performance.

At the core is Smart.Elastic.Technology (S.E.T) - a discreet 2 mm heating line integrated seamlessly into the sock to diffuse gentle warmth around the toes while preserving a natural, uncompromised fit. A polyamide-rich construction ensures excellent foot support and a secure, stay-put hold during high-intensity skiing.

These socks feature 200-needle high-definition knitting for a smooth construction with no cut threads, plus carefully balanced tension that provides a snug fit around the feet and legs. Their thin, technical design improves contact with ski boots, enhancing precision and responsiveness. Combined with efficient insulation and advanced moisture management, they keep feet warm, dry, and comfortable throughout long, demanding sessions on the mountain.
