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 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. 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.Sizing S (EU 34-37) M (EU 38-41) L (EU 42-45) 4 Degree™ Elite Fit System For a dialed, performance-oriented fit with flex zone at ankle joint Mesh Venting Mesh ventilation zones provide optimum moisture management and maximum breathability Shred Shield Shred Shield helps reduce wear from toes Women Specific Fit Women's specific fit; narrower heel and slimmer fit Seamless Seamless construction provides support with stretch for mobility and comfort Indestructawool™ Indestructawool™ technology features a patent-pending construction method for exceptional durability and comfort Light Cushion Our lightest full-sole cushion for varied terrain and maximum end-use versatility Indestructawool™ technology with extended durability zones 4 Degree™ elite fit system for a dialed-in, performance-oriented fit Additional body-mapped mesh zones for added breathability Virtually Seamless™ toe for enhanced comfort Comfort welt with 'stay put' fit Women's specific fit Height: 5.5" Weight: 0.058 kgs Country of Manufacture: United States 54% Merino Wool 12% Nylon 30% Recycled Nylon 4% Elastane CARE Machine Wash Warm.
