Paul Kelly I've had foot, knee and occasional back pain for a long time (more than 5 years). I purchased my first set of arch supports yesterday (11/23/11) and started breaking them in today at work (yes, on Thanksgiving!). I was surprised at the end of the day that I had NO pain whatsoever! Surprised because I never even thought about it. I also goofed and wore the strengthener for 90 minutes instead of the recommended 15-30 minutes. They seemed ok, but I still changed into the maintainers for the remainder of the day. I would highly recommend these supports to anyone who has leg/foot pain. My normal day usually starts with 2 Aleve (tm), but I did not take any today (the last one was on Monday). WOW, what a difference!
