Experience maximum warmth and protection with these Merino wool hiking socks, featuring Indestructawool durability and a performance-oriented fit.
The Smartwool Hike Full Cushion Crew Socks, formerly known as the PhD Outdoor series, are engineered to provide maximum warmth and protection for high-mileage trail days. Crafted from a technical blend of responsibly sourced, ZQ-certified Merino wool and recycled nylon, these socks offer natural temperature regulation, moisture management, and odor resistance. The full-cushion design extends throughout the entire sock, absorbing impact on rugged terrain and providing an essential insulation layer for cold-weather hikes. Featuring Smartwool's top-tier performance technologies, including the 4 Degree Elite Fit System and Indestructawool durability zones, these socks are built to stay securely in place while outlasting your longest adventures. Updated mesh zones enhance breathability, while the Virtually Seamless toe ensures a smooth, blister-free fit inside any hiking boot.
