The Smartwool Women's PhD Outdoor Light Crew is a lightly cushioned sock for paved walking trails or day hiking trails. The light cushion is just enough for a full day of light walking or hiking, with a 4 Degree™ Elite fit system covering your arch, lower instep, upper instep, and ankle. Talk about going above and beyond heel to toe. The cozy blend of merino wool, nylon, and elastane will wick sweat away from your foot, leaving you dry and comfortable for the whole day. PhD's aren't just for doctors.
