i would just like to add, a final question about my flat foot. On the interior of my feet (both of them) right above the arch and a little below the ankle bone i have another bone, it is quite visible, and i usually dont see this in other people.. this bone is more evident on the flat foot aswell… is it just my anatomy, or are both things related?

Edit: i just happened to find some info about this myself, its an accesory navicular, but it doesnt really hurt or anything, so i guess it wont cause any problem. 🙂
