SmartWool was born with comfortable performance in mind. The 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 to care for. SmartWool socks offer supreme comfort and performance. SmartWool feels good.

This version is perfect for lightweight hiking or aggressive walking. Medium weight cushioning on the foot and toes provides protection in high-friction areas, while a thin flat knit instep provides a sleeker fit.
