Product Info

Whether you're an avid cyclist, an obsessive runner, or an indiscriminate enthusiast you know that a bad blister can lead to bruising and can even mean momentarily putting your favorite pastime on hold. That's why Swiftwick developed the Swiftwick Aspire Four Bike Socks. Crafted from wicking Olefin the Aspire Fours feature a 200-needle density meaning trail debris and foreign material won't find its way into your socks, causing irritation and blisters. Plus, they feature Swiftwick's Signature Double Welt Compression Cuff that works like a second skin to support the 200 ligaments and muscles in your feet.
