Socks

Our Classic Hike Full Cushion Crew socks focus on comfort and durability, so you can go farther on every hike. Responsibly sourced, ZQ-certified Merino wool keeps things soft, while recycled nylon keeps it all sustainable. And full cushioning on the entire sock adds the warmth and protection you need and love. Stay cozy out there with our updated Classic Hike socks.

Over 25 years ago, Smartwool invented the original Merino wool performance sock—the Classic Hike. The Classic Hike remains mostly unchanged and certainly unmatched in comfort. But today, it’s getting upgraded. That upgrade starts with recycled nylon—creating a more sustainable (but just as comfortable) sock. They’re also made with responsibly sourced, ZQ-certified wool that was grown with a focus on ensuring environmental, social, and economic sustainability while also taking the best care of our Merino sheep. This is a cozy, capable classic that is never going out of style.
