“Have had some other Swiftwick socks (Aspire 4) and love them. But these are not as good. Much thinner than my others and the heel doesn't stay up very well. After an hour or so the heel falls under my heel.”
Thanks for your feedback, and we're sorry that your recent ASPIRE Zero socks weren't like your others. All of our socks are backed by our "Best Sock You Will Ever Wear" guarantee, and we will reach out to you directly to help resolve this issue.
