Our new and improved Hike Light socks, formerly PhDA(R) 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. 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 without sacrificing the perfect sock fit. Less pressure. More performance.
