The SmartWool Women's PhD Ski Medium Pattern Sock delivers warmth and mid-level cushioning, so the cold won't chase you off the mountain before you're ready. Made from a cozy merino wool blend, these ski socks deliver not just softness and warmth, but also the moisture-wicking power and odor-control that merino is famous for. SmartWool's Indestructawool technology places more durable material in high-wear zones to provide exceptional durability and comfort.
