The Smartwool Women's Hike Light Cushion Mid Crew Socks are a lovely combination of style, performance, and comfort. At a height of 5.5 inches, these socks feature a mid-crew design that is super soft thanks to the special blend of merino wool, nylon, recycled nylon, and Elastane. Each sock is designed for long-lasting durability and breathability, thanks to multiple mesh ventilation zones. With the innovative Shred Shield design, you can say goodbye to holes in your socks. Wash these socks on the warm setting of your machine inside-out and tumble dry low.
