It's almost painful to go a whole day without getting a run in. So when you're faced with a busy schedule and the only time you can squeeze in that daily fix is during the hottest part of the afternoon, pull on the Darn Tough No-Show Mesh Light Running Sock. Lightweight and extremely breathable, this performance sock features mesh knitting to keep your feet cool when the blacktop radiates heat. The merino wool blend pulls sweat away from your feet and dries quickly for comfort as you push yourself mile after mile.
