Perform with the power and comfort of responsibly sourced, ZQ-certified Merino wool in our Hike Light Cushion Crew socks. Formerly known as PhD® Outdoor, we've updated our best hike socks to include more sustainable materials with the addition of recycled nylon, improved durability, updated mesh zones, and an even more perfect fit. But, don't worry. Our fan-favorite sock technologies aren't going anywhere—offering you the comfort and performance you expect from Smartwool. The crew height also adds extra coverage on the trails and light cushioning on the entire bottom of foot helps keep you comfortable when the ground isn't—helping you to hike on (and on.. and on..)
