The Swiftwick Aspire Twelve Skate Socks are designed with your foot's intricate anatomy in mind. Created on a 200 needle machine, the Aspire sock features seamless toe construction to prevent bunching in the toe and a sculptured footbed for maximum comfort. Swiftwick's Managed Compression is proven to reduce swelling and improve circulation. The Aspire sock is made with olefin, a fiber that retains less than .01% of its weight in moisture and helps to effectively wick sweat without the use of chemicals.
