Do what feels natural in the Hike Light socks. Formerly known as PhD Outdoor, they’ve added enhanced features to the responsibly sourced, ZQ-certified Merino wool socks to help you stay comfortable, breathable, and able to hike any way you like. Improved durability and mesh zones work together with the top sock technologies to bring you a wool hiking sock capable of climbing it all. Light cushioning along the entire bottom of the sock brings more comfort to your favourite hiking shoe or boot. A crew height helps add extra coverage on the trails and recycled nylon makes this sock more sustainable than ever before. Gear up to go far with Smartwool.
