After market running shoe inserts (insoles), worth it or not?

Thanks for the reply! I stand corrected… I never new you could create arches in flat feet.

Always learning new crap from this forum…

I’m sure the Dr. I went to had a vested interest in selling me custom orthotics, and they did work to eliminate the problem. However, it would have been nice to know about some exercises to strengthen the foot to help my situation.
