A few years ago I went to a podiatrist in Pasadena who referred me to an orthotic specialist to help with my flat feet which seems to be the cause of occasional ankle pain due to over-pronation. But the orthotics I received did not seem to fix my problem – they were flat orthotics with a “ridge” down the middle to “relax” my foot. What do you recommend for someone with flat feet? I believe my flat feet are also the cause of my knee pain since the inward collapse of my ankles puts stress on my ACL’s. Thanks.
