My feet are so flat I have a negative arch and the heating/molding serves only to take the edge off the support so it doesn't feel like you're standing on a superball.

Because of the flat feet, I've had more than a few problems with feet/ankles due to pounding of running and playing basketball. My sports orthopedist/D.P.M. years ago recommended these before going to $300-500/pr. custom orthotics and I've never looked back. I wouldn't dare say that they will work for everyone, but they're reasonably priced enough to try given the extreme cost of the prescription alternative.

Good luck,

Steve.
