This reliable outdoor sock will keep your feet cool in summer and warm in winter thanks to the advanced merino wool blend. It feels like it's made of plush but weighs less. It has a terry cloth lined, reinforced sole which has a shock absorbing effect. This sock reaches over the calf and protects you from the weather. Our technology for a non-slip upper prevents the socks from slipping or cutting into the skin. Perfect for hiking, walking or work.
