The Smartwool Ski Targeted Cushion Winter Adventure Print OTC Sock is built around what actually wears feet out over a long day in the boot, starting with a merino wool blend that manages moisture and regulates temperature instead of leaving feet damp by midday. A Virtually Seamless(TM) toe removes the seam that usually rubs raw over hours of skiing, and targeted cushioning with Indestructawool(TM) durability keeps the high-wear zones supported. Over-the-calf coverage and the 4 Degree(TM) Elite Fit System round out a sock built to last as long as the day does. What Our Gearhead(R) Experts Are Saying:"I've worn these through a full day of lift laps without a single toe-seam hot spot, and my feet were still dry pulling my boots off at the end. That's the merino and the seamless toe doing their job together, not just one or the other."
