The Swiftwick ASPIRE is the classic multisport sock. Swiftwick has created a sock that has taken each aspect of the human foot in mind and constructed to meet the needs of any athlete. Building on the tradition of manufacturing the best socks made in the USA, the Aspire features 200 needle construction, no seams, Olefin fiber toe, heel and footbed for superior compression. The thin channeled upper promotes air flow and the double welt compression cuff keeps the sock in place. Swiftwick considered smaller feet, the narrow foot and athletic activities that demand compression, but less padding in the toe box. They adjusted the formula for key fibers, more than doubled the olefin content and once again, produced the best sock you will ever wear, guaranteed. For athletes, the obvious choice is Swiftwick Aspire. Two-inch cuff.
