Cross-country socks for maximum performance on the trail: Merino Nordic 2 was specially developed for you as a cross-country skier. The high-quality merino wool provides natural warmth, regulates temperature, and keeps your feet pleasantly dry even in icy conditions. The innovative 3D knitting technology improves air circulation and protects you from overheating during intense training sessions.
The anatomical left/right design fits your foot perfectly. Thanks to the flat, hand-linked toe seam, there are no pressure points – ideal for long tours. Cushioned zones in high-impact areas offer added protection, while the wide active cuff and midfoot ring band ensure a secure fit – without slipping.
Whether you prefer classic technique or skate skiing, the Merino Nordic 2 socks deliver top comfort, reliable warmth, and full freedom of movement – kilometer after kilometer.
