Sidas Nordic Performance X Jessie Diggins

Designed in collaboration with Jessie Diggins, these Nordic ski socks are built for athletes who want comfort, confidence, and connection to the sport. Created for Nordic skiing and everyday training sessions, they help wick moisture, stay securely in place, and reduce the risk of blisters so you can focus on enjoying your time on snow.

A grip strip above the ankle improves contact between the sock and your skin, creating a secure, second-skin feel. Ventilated mesh zones in the forefoot help manage moisture during climbs and longer sessions. With a firm but comfortable tension and a low-profile thickness, these socks adapt naturally to your feet without affecting the fit of your ski boots.

Made using a blend of organic merino wool and recycled fibres, these socks are designed to take care of your feet while also keeping sustainability in mind. They’re durable, comfortable, and ready for long days of training, racing, or skiing with friends.

Precision & Comfort
These socks are knitted with 200 needles and feature In & Out construction (no cut yarns) to create a smooth, comfortable feel against the skin. Their supportive tension helps keep the sock in place throughout your session, while the minimal thickness improves contact with the ski boot.

Blister Prevention
Blisters are often caused by friction and moisture. The combination of skin-friendly yarns, secure tension, and effective moisture wicking helps reduce movement inside the boot, keeping feet drier and more comfortable.

Warmth & Breathability
The merino wool blend provides natural warmth while remaining breathable, helping regulate temperature and keep feet comfortable in changing winter conditions.

Unisex sizing available in six sizes to help ensure the right fit for every athlete.
