One of our most tech-savy snow socks, the new Function X was re-engineered to provide max comfort and warmth for resort skiers and riders. Made from midweight merino wool, these ultra-smooth socks make all the difference if you decide to head back out after lunch. Terry cushioning in the shin and the 'X' on top of the foot provides warmth while added heel durability protects you run after run.

• Men's over the calf socks average 17 in. from heel to cuff - expect them to cover the leg to just below the knee.
• A performance fit means no slipping, no bunching, no boundaries. Here's to feeling connected and comfortable in your boots run after run.
• Merino Wool has a natural ability to move heat and moisture, keeping skier's and rider's feet warm and dry.
• All-season performers, midweight socks naturally adapt to keep your feet at the right temperature.
• The "still" in Still Made in Vermont, USA is personal. All the socks at the VT-based Mills - can't imagine it any other way.
