I really like this idea. I haven't found a pair of Nike's that have been comfortable though. I guess I could give them another try, they seem very narrow to me, it might be worth it to try a wide. I'm too big for running, but it would be nice to know how good the hikes and walking are doing for me. I'm going to do my research! I can't wait until I'm small enough to run without blowing out a knee!
