Swiftwick Performance Seven - Crew

The Swiftwick Performance Seven Crew performance running sock is a lighter version of Swiftwick's successful Performance Run sock line. Knitted at 200 needles, Swiftwick running sock has the highest stitch density you'll find in any running sock on the market today. Benefits to you include a softer, denser, and more durable sock. Extra compression (21.1 mmHG) promotes blood flow which increases your performance by reducing foot and leg fatigue. Heavy use of the high performance fiber, Olefin, moves moisture like a champ and has a very low friction coefficient. Second-skin feel prevents shifting or bunching, eliminates the risk of friction blisters, and makes your shoe fit more comfortably.
