PhD Run Light Elite Crew Sock

The culmination of years of field testing, prototypes, and running experience, the PhD Run Light Elite Crew Socks are Smartwool's most advanced run socks yet. Merino wool offers unparalleled temperature regulation to help your feet stay cool from start to finish, and the 4 Degree Elite Fit System offers excellent stretch and recovery so your socks don't slip or bunch halfway through your run. Mesh venting offers relief on hot weather jaunts, and Light Elite cushioning offers targeted impact protection at the ball and heel of the foot to elevate comfort with minimal in-shoe volume. And with durable Indestructawool technology, these socks are built to go the extra mile.
