Swiftwick Aspire FOUR

Swiftwick believes that socks make a major contribution to comfort, performance and foot health. Minimizing or reducing hotspots, blisters, and fungus are clear goals. The Aspire FOUR is a tall-ish quarter crew sock designed with the needs of cyclists and trail runners in mind. Known for it's minimal cushioning and high compression level, the Aspire FOUR is Swiftwick's best selling warm weather cycling sock.

In every Swiftwick sock there are common characteristics. First is a contoured compression fit that is designed to eliminate bunching, while supporting every structure and aspect of the foot. Second is fiber first moisture wicking, which means the properties of each fabric must promote wicking, or be truly hydrophobic. The high performance fibers are then sculpted into breathable designs constructed to move moisture. The third is that the first two combine to deliver blister-free performance. The application of the fibers and wicking properties mean little if compression and support don't deliver a true performance sock.

The Aspire FOUR employs three materials: 67% Nylon, 28% Olefin, 5% Spandex to achieve the desired characteristics. This also is the tallest style with Swiftwick's signature double-cuff construction, which means it will stay up and deliver effective compression and support. This minimal cushion sock was designed for high-tech footwear with a close natural fit where staying dry and supported at all times is ideal.
