Find your comfort zone on every hike with the women's Hike Light socks. Formerly known as PhD® outdoor socks, these hiking socks are packed with all their tried-and-true sock innovations, like their Indestructawool™ technology for enhanced durability, their 4 Degree™ Elite fit system and women's-specific fit, and their Virtually Seamless™ toe for even more comfort. They've extended durability zones and updated mesh areas to help maximize breathability without sacrificing the perfect sock fit. And soft responsibly sourced, ZQ-certified merino wool handles the rest, working hard when you do. With a low ankle height that pairs perfectly with your low-cut hiking shoes, it's easy to stay comfortable on even the longest, most advanced hikes.
