The insoles are hard and uncomfortable, but the worst part when you call them you get a person who dosen't speak or understand english. The worst they sent you some joint support formula pills that I did't ask for. They charge my card twice. You try to talk to them and they give you the run around. It's a rip off at it worst kind. I am on a fix income and the made that second unauthorized charge making me have a overdrawn. This is the worst product beware.
