Swiftwick Aspire Zero Tab Sock
Aspire Zero from Swiftwick is created with high-performance polyester fibers that wick away moisture and work to keep your feet cool and comfortable. Thin profile is designed to fit into any technical shoe with a barely-there feeling. Firmly hugs the contours of your feet to support the arch and help reduce fatigue. They are made with a micro tab that prevents contact with the back of the shoe for maximum protection from blisters. These socks are made in the USA with a focus on sustainable production practices.
