I got some custom orthos from a pod. and my insurance covers some but total cost was like 350, and they do the trick. Problem with the superfeet and alike is they can work for some but not most. Flat, med arch is just one part of feet, I will spare you the tech terms but some feet have a tilt to them that basic insoles do not account for. As for running shoes go to a good store like Mike suggested but if you have an ortho you will want to stick to a neutral shoe, you will get the stability you need from your ortho, a roomy toe box is good too, it mimics the hole running barefoot this and lets your toes spread like they should.
