Say bye to boring, run-of-the-mill running socks. We've brought our proprietary printing 360° technology to our trail-crushing, race-day-worthy run socks—giving you the performance you expect from Smartwool, with a fun little twist. Our Women's PhD® Run Ultra Light Print Crew socks feature Indestructawool™ technology for added durability, Shred Shield™ technology to reduce wear from toes, and body mapped mesh zones for added breathability.
