I LOVE these shoes. I have several different pair now. They work gret. My knees don't hurt when I wear them, at all. The only thing I hate is having to take them off. I have gotten these for family members with knee and back problems, and they LOVE them. I would recommend them to anyone and everyone, especially if you have knee or back problems.
