Nike 3 Pack Dri-Fit No Show Running Socks A thick terry sole provides ample cushioning during foot-punishing cardio workouts helping you stay comfortable longer. Arch compression offers targeted support. Dri-FIT Technology helps your feet stay dry and comfortable by pulling sweat away from your skin to the fabric's surface, where it quickly evaporates. Fabric at the sole is engineered to grip the inside of your shoe, helping to reduce slide during your workout. Soft mesh at the top offers cooling ventilation.
