Well, you can deal with PF by wearing foot casts and immobilizing your foot, allowing all the little muscles to atrophy. Or you can go barefoot and let all the little muscles get strong. It's funny but most people get PF while wearing supportive shoes (that also throw the body's balance out of whack because of the raised heel) and then think that even more support is the answer.
