UYN ONE ski socks encompass all the features you need to blaze down the slopes at the best of your ability. Designed using the innovative ZEROCUFF technology, they ensure a perfect fit on the calf without obstructing blood circulation and without leaving marks. This increases sensitivity and decreases foot fatigue, giving you a better feeling and perception in the boot. The combination of Merino wool with our special NATEX fiber makes UYN ONE ski socks extremely soft and thermoregulating, ensuring exceptional comfort and warm feet even on the coldest days.
