My friend has flat feet, and was told during his RAAF medical that it would rule him out. He objected, explaining that they were not causing any problems. He had to show some dexterity by picking up a pencil between his toes or some such nonsense, but basically talked his way past the problem. Admittedly it was years ago, so not sure whether things would have changed.
By the way, he still has no problems with his feet!!
Good luck
