Ecosox World's Most Eco-Friendly Sock (Bamboo Viscose & Merino Wool)

SIZING: Medium fits Women's shoe sizes 4-10.5 & Men's shoe sizes 3-9; Large fits Men's shoe sizes 9-12 & Women's shoe sizes 10+. From an eco-friendly combination of viscose from bamboo and merino wool, these socks are not only green but warm and cozy too! Bamboo naturally helps to fight against odors and static which helps to fight the formation of blisters. Rather than being knit from a little bit of each fiber, we have actually developed a fiber spinning both of these materials into one. Your feet will be warm in winter and cool in summer thanks to the thermo-regulating properties of both bamboo and wool. Great for hiking, construction & industrial work, as well as leisure wear!
