DESCRIPTION

From the trail to the office, the Smartwool PhD Outdoor Light Crew is an everyday all-star sock with tons of tech benefits. The 4-Degree Fit System utilizes athletic-shoe technology, creating a four zone support system in the ankle, arch, upper and lower instep. Stretch mesh along the top of the foot maximizes breathability, and WOW (Wool-On-Wool) double-layer impact padding in the toe and heel cushions your stride.
