I have flat feet, I pretty much have no arch at all. I used to over pronate very bad, that has become way better; however the fact remains my feet are still very flat. I know the anterior and posterior tibialis effect pronation. I know, that reverse calf raises target the tibialis. If I were to do reverse calf raises and maybe some other tibialis strength work without doing any calf isolation work, could that help lessen the flatness of my feet?
