Get the most out of every ski day with the Ultra Warm Performance S.E.T® heated ski socks—engineered for expert skiers tackling extreme conditions. These thin, high-performance socks feature Smart.Elastic.® technology for a precise, no-bulk fit inside ski boots, delivering exceptional comfort, control, and snow feel. A discreet integrated heating line delivers gentle, targeted warmth to the toes without affecting fit or performance.

Built with advanced thermo-regulating knit construction and natural merino wool, these heated ski socks offer outstanding insulation, breathability, and temperature control. Durable polyamide fibers enhance support and stability during high-intensity skiing, while strategically placed heat-retaining and breathable zones work in harmony with Smart.Elastic® technology. Moisture-Vent technology actively wicks sweat away from the skin to keep your feet dry, comfortable, and blister-free all day long.

Designed for demanding skiers, the Ultra Warm Performance S.E.T® socks combine a slim profile, superior comfort, and reliable warmth. The subtle heating system and performance-driven materials ensure warm, dry feet without sacrificing responsiveness—so you can ski longer and harder in the coldest conditions.

Each pair includes two S-PACK 1400B rechargeable batteries, providing up to 9 hours of adjustable warmth. Bluetooth compatibility allows easy heat control, and a USB charging cable is included for convenient recharging.
