Description of SmartWool Ski Racing Light Socks - Women's SmartWool was born with comfortable performance in mind. Their founders were New England ski instructors struggling to keep their feet warm. After trying a variety of materials, they rediscovered an age-old classic: wool. But while these socks may have been warm, they were itchy and shrank. So they worked on a process to make them soft and easy care. SmartWool was born on a simple tenet: keeping feet comfortable on the slopes.
