Great socks!


I run in these several times a week. Short runs, long runs, doesn't matter, they are comfortable and work as advertised. I haven't gotten any blisters, they do not itch, and even running in the heat/humidity of Texas for a few days, they were fine. Great socks, I just recently order a couple more pairs!
