The Run Lite-Mesh sock is our #1 selling run sock. It’s the favorite because it’s the ideal balance between thin and thick running socks. Engineered with dense terry loops underfoot for miles and miles of comfort. Mesh Stripe Vents over the foot and under the arch provide remarkable breathability, helping keep feet cooler, drier and more comfortable. This sock can be used for casual or long distance runs and has helped earn two World and two National Records!
