The women’s PhD Outdoor Light Micro Socks by Smartwool are made for life on the trail. Smartwool constructed them with their brand new Indestructawool technology. This technology is a durable weave of wool-based yarn, helping these socks last you even longer. Mesh zones help maximize breathability while the Virtually Seamless toes pair well with your hiking boots – preventing blisters. The women’s-specific fit with a narrower heel gives an overall slimmer feel, great for ladies with smaller feet.
