Socks

The Classic Hike Zero Cushion Liner Crew hearkens back to our original construction but adds in recycled nylon for strength and durability while reducing environmental impact. This liner has an elasticized arch brace so your foot will enjoy a secure fit, and it will give you a flat knit toe seam for additional comfort. When you’re ready for your next hike, be sure to grab a pair of these responsibly sourced Merino wool socks to make the most of each mile on the trail.

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.
