Our new and improved Hike Light socks, formerly PhD® Outdoor, offer a women's-specific fit and bring you enhanced features to maximize comfort and help you hit the trail at the highest level. We've extended the durability zones to make them cover even more of the sock—offering the same comfort with even more strength. And updated mesh zones help improve breathability and minimize pressure without sacrificing the perfect sock fit. Add these features to a light-cushioned sock that already provides the highest degree of comfort, fit, and durability, and it's never been easier to go far and feel good.
