The Swiftwick Performance running sock is Swiftwick's everyday go-to running and cycling sock. Great place to get the full Swiftwick experience.

• Swiftwick running socks are knitted at 200 needles, the highest density you'll find in any running sock on the market today. The benefits include a second-skin feel and 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, which moves moisture like a champ and has a very low friction coefficient.
