These are the best running socks I have ever used. I started using them after I noticed I was getting lots of blisters from running. Started using these socks and noticed an immediate difference. I still get blisters sometimes, but not nearly as much, and my feet don't hurt nearly as bad after a long run as they did when I was wearing other socks. They also work well for hiking, and help protect my feet from the rocks that can press into trail running shoes. I recommend these to every runner.
