Say goodbye to boring, run-of-the-mill running socks. We've brought our 360-degree printing technology to our race-day-worthy run socks to give you the performance you expect from Smartwool with a colorful twist. Our Women's PhD® Run Ultra Light Print Micro socks feature Indestructawool™ durability technology, Shred Shield™ anti-wear technology to reduce wear from toes, and body-mapped mesh zones for added breathability—making this one of our most technical running socks.
