Dudley Moore, the actor, had a club foot. it had been treated as a child, but it was still smaller, and not 'normal'(at least in his estimation)

he never allowed his foot to be photographed... (watch 10 again.. or Arther--he runs on the beach but we never see his feet, except from a long distance,(and then then he is wearing shoes! and while he is stumble-footed as a drunk, we never see he faulty footwork up close...

i don't think there is any noticable difference in his gate, (maybe an orthopedist would notice one) so what ever treatment he recieved, it must have worked.
