The Women’s SMARTWOOL PHD OUTDOOR LIGHT Crew Socks are essential for those chilly days out on the trails. Indestructawool technology makes them extra durable. The women’s specific fit features a slimmer fit and narrow heel for a more comfortable fit. The light cushion under the foot helps reduce wear and provides added cushioning on those long hikes. Made from merino wool means they are breathable, stay dry, and keep your feet cool on hot days, and retain warmth on cold days. The body-mapped mesh zones provide additional breathability and moisture management. The crew height rises to the calf for added warmth.
