When you need a ski sock that cuts weight without skimping on comfort, turn to the SmartWool PhD Ski Light Sock. Constructed using SmartWool's new Indestructawool technology, which places more durable materials in high-wear zones, these socks are incredibly comfortable and durable. Light cushioning at the shin and foot protect you from stiff ski boots, while the merino wool construction provides warmth and moisture-wicking power. With a 4 Degree elite fit system for greater stretch and recovery and mesh ventilation zones, these socks will keep you feeling good whether you're nailing a few pre-work laps or enjoying a week-long ski trip.
