REVISED REVIEW: After I posted the two-star review (below), much to my surprise, without asking for it or being told about it, I was immediately issued a refund from Swiftwick. It appears that I had misunderstood the purpose of the socks I bought. Even though they had pictures of national parks on them, they are not intended to be hiking socks. Completely a mistake on my part. Not only did I get the refund, but they sent me a pair of hiking socks at no cost! These hiking socks are great, the customer service fantastic, and I am now a loyal fan! Thanks, Swiftwick for all of this, especially because it all began because I was so dazzled by the graphics on the Vision socks that I failed to read their intended purpose. I'm off to hike in my new socks and to tell my hiking group about my incredible Swiftwick experience! ------- INITIAL REVIEW Very pretty but disappointing because I like all the other Swiftwick socks I have. The Vision socks are thinner than I expected or would ever wear for hiking or other athletic endeavor. They feel like there is a lot of nylon in them. Wouldn't buy these socks again.
