I typically wear a few of the other brands of running socks, but decided to try these. I bought two pair and I have to say that they are outstanding. I've had them for about a month now and run, walk or bike most everyday. I haven't seen any issues, threading coming loose, or shrinking with wash. When walking or running in them, they help provide a little extra padded bounce in my step, and I'm going to order a few more pair. I've even caught my wife wearing them around the house.
