Without being any kind of foot specialist, if you experience rubbing you could try the spot-heating and punching method, you can do it at home with a heat-gun and the back of a screw-driver as demonstrated here (I know there also is a VH vid about this somewhere):
As the Mako can be baked multiple times this shouldn't do any damage (as long as you don't burn them) at all and might be worth a shot.
