Swiftwick Performance Four

Swiftwick's combination of synthetic and natural fibers are up to 10 times more hydrophobic than cotton, preventing water absorption and moisture retention in the sock's structure. Optimal foot health requires keeping feet dry and blister-free in all weather conditions.

Swiftwick uses finer grade, stronger materials – Olefin, Nylon, and Spandex­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­-with a 200-knit construction to create managed pressure on the legs, ankles, and feet. Their compression footbed cradles your foot's arch. Compression cuffs on each sock prevent unnecessary movement, making the sock the most form fitting on the market. It also promotes blood flow to the feet, actually improving your circulation in the lower part of your legs, thus increasing performance while you compete. Improved vascular performance and blood flow also means reduced leg fatigue, which speeds recovery after a long run or ride.
