Swiftwick has great socks and the customer service and provided warranty are top notch. One of the best in the sock business! My favorite socks: The Swiftwick Aspire socks are my go to socks for cycling, running, walking, and hiking. The socks have a light to medium compression fit and have wick away characteristics. I never have to worry any rubbing or blisters when wearing the Aspire socks because they stay in place. I personally use the Aspire Four, but I would imagine that the Two and Zero work just as well. My only suggestion for Swiftwick would be that I would like to get a highly visible Orange pair of these. Swiftwick used to make Orange Aspires many years ago. So, Swiftwick. How about some High Visible Orange Aspires in the Fours? Cheers!
