Bring the natural performance features of responsibly sourced ZQ-certified Merino wool with you on every hike in the Performance Hike Light socks by SMARTWOOL (formerly known as PhD® Outdoor). Thermoregulation, sweat management, and odor resistance join forces to help keep you comfortable all day long, while innovative sock technologies and light cushioning along the entire bottom of the sock help you take care of your feet on every hike.  The hiking sock construction has also been updated to be more sustainable with the addition of recycled nylon, more durable, and more breathable—without sacrificing that tailored-to-you fit. So you can tackle more trails and enjoy more summits.
