Designed to provide a performance fit for skiers on varied to difficult terrain, Thorlos Think Ski Socks offer a lower density padding, making them more suitable for other activities such as Cross Country, Ski Touring, and Telemark also. Thin cushioning in the ball and heel provides warmth, shear protection and comfort; more thin cushioning at the shin protects against shin bite and a flat knit instep and arch gives better fit and circulation.(10/11)
