I'm 20 years old and have flat-feet. I have pain in my back, my hips, my knees, my ankles and I get charlie horses under my arches sometimes. I've tried it all now (the $200 orthotics from the poditrist, the walk-fit orthotics, good shoes etc...)and I'm really starting to get annoyed. Does anybody out there have any new suggestions, was there something I missed?
