The new and improved Hike Light socks, formerly Ph D Outdoor, offer a women's-specific fit and bring you enhanced features to maximize comfort and help you get after it at the highest level. Smartwool has 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 without sacrificing the perfect sock fit. Less pressure. More performance. Add these features to a lightly 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.
