Running Lab Performance Midweight No-Show Running Sock SIZE:Small Rocker profile for smootherInformation Running Lab have their own branded sock and we think we made ours just right. Not too tight and not too loose. This sock features a Y seam in the toe and in the heel, because all socks should have that! The right amount of cushioning under the foot and a lighter mesh up top to help the foot breathe. We also added an arch wrap just to make sure this sock is locked down and ready to move without you thinking about the sock! Sock Size SM MD
