Product benefits

The high-performance Ski Ultrafit ski socks are knitted with 200 needles and entirely manufactured without cut threads to provide comfort and better precision when skiing. Compressive and ultra-low volume, these ski socks work like a second skin and offer a direct connection to your ski boot. Organic merino wool and recycled polyamide are part of the EcoTech design of the socks, thanks to the incorporation of recycled fibres in their composition.

The Ski Ultrafit socks also aid blood circulation and muscle stabilisation thanks to the Compressives Tension technology (20 to 30 mmHg). This leads to better recovery for the skier, less muscle vibration and better performance.

These performance ski socks have an outstanding precision. This is dependent on the sock's knitting, thickness and tension. Knitted using 200 needles, one of the highest definitions available for socks, and entirely designed without any cut threads (In & Out construction), their tension is strong to provide a perfect fit to the feet and legs. Finally, their thickness is minimal to improve contact with the ski boot, while still remaining comfortable.

The silicone grip strip on the bottom of the foot guarantees contact with the insoles and ski boots for optimal stability. The foot remains in contact with the insole for better precision and transmission.

The merino wool used in the socks provides warmth and moisture wicking for optimal breathability of your feet.
