The Teko Evolution Merino Midweight Hiking Sock is a good hiking sock keeps feet warm, dry, reduce friction between the foot and the boot, and is comfy (no itchy, scratchy material need apply). Feet sweat a lot as evidence by their 250,000 sweat glands for both feet combined! It’s important to have good hiking socks which allow excess heat to escape the foot and move the moisture away to the outer layer of the sock. Whether mountaineering, hiking, ice climbing or backpacking, warmth is an issue, especially for those who have cold feet or poor circulation. Feet take a pounding on the trails and in the mountains, so it’s important to give them some love with soft, comfy fabrics.
