I didn't like this product at all. I chose it because I have leg pain a lot, and I though this would help improve it. The first day was ok -- they hurt my heels some, but not too bad. The second day, they hurt my feet and my heels. I decided to try to keep wearing them, thinking that maybe they had to be broken in. After about five days of wearing them, my legs and feet hurt worse than they did before. I know the result was supposed to be the exact opposite -- but unfortunately it wasn't.
