Swiftwick – Aspire Zero Black

The ASPIRE™ Line is thin and light for serious runners and cyclists, yet still perfect for athletes of any sport. Our Managed Compression™ prevents bunching and hot spots by supporting all 3 arches in the foot. Our Linked-Toe technology prevents blisters by eliminating bunching in the toe-box. Our socks are knitted at 200 needles, the highest you’ll find in socks. The higher the needle, the tighter the knit. This high-gauge construction produces a softer, denser, more durable garment with outstanding graphic detail. The result is a sock designed to fit your feet perfectly while helping you do what moves you.
