The PhD Running Ultra Light Micro from Smartwool is a minimal running sock, specifically designed for a women's foot. Non-cushioned and at a micro height, this sock is perfect for mild weather and shorter distance road runs. Thanks to Realiwool Technology in high density impact zones, these socks are sure to outrun your running shoes. Includes a padded Achilles tab for protection.
New 4 Degree Elite Fit System uses two elastics for greater stretch and recovery to keep the sock in place, and utilizes a supportive system that provides an incredibly secure, comfortable fit around the heel, arch and instep
Patent pending ReliaWool Technology in high impact areas provides the longer lasting protection to keep feet comfortable
