The Ski Heat LV heated sock is designed for skiers who suffer from cold feet and demand both comfort and precision. Developed from the analysis of 300,000 feet and 15,000 shoes, this sock ensures an ideal fit between your foot and ski boot, delivering warmth without compromising performance.

A discreet heating element on the outside of the sock provides soft, constant warmth under the forefoot, keeping toes comfortable throughout the day. Made from a hybrid blend of natural wool and technical fibers, the sock balances insulation, breathability, and moisture management to keep feet warm, dry, and fresh.

The compressive 15–20 mmHg fit improves sensation, precision, and foot-to-boot connection, while SynergyFit™ Concept eliminates bulk by reducing padding and excess yarn. The result is a perfectly anatomical fit that works in harmony with your feet, insoles, and ski boots.
