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. And that upgrade starts with recycled nylon—adding more sustainability to Smartwool's favourite socks. 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 women's cozy, capable classic that is never going out of style.

Smartwool's Hike Full Cushion Crew socks, formerly PhD® Outdoor, use cushioning on the entire sock to help maximize warmth and protection.

These responsibly sourced, ZQ-certified Merino wool hike socks are built with our top sock tech, including Indestructawool™ technology for enhanced durability, our 4 Degree™ Elite Fit System for a dialed-in, performance-oriented fit, and our Virtually Seamless™ toe for maximum in-shoe/boot comfort.

Smartwool have updated their hike line by improving mesh zones for additional breathability, as well as creating a new ply structure that reduces pilling while enhancing hand-feel and comfort. Not to mention, Smartwool's best-feeling, best-fitting hiking socks are now made with recycled nylon—making these socks more sustainable than ever. Now that's something you can feel good in and about.

Smartwool's Classic Hike Extra Cushion Crew sock features a dense cushion for adventurers who need more padding in their favorite hiking shoe or boot.

Elevate every hike with this cozy, capable classic.

The Classic Hike Zero Cushion Liner Crew hearkens back to Smartwool's original construction but adds in recycled nylon for strength and durability while reducing environmental impact.
