Hi my Son's right foot is pointed outward and drags a tiny bit and He limp because of severity of angle. He claims it is nothing but he has to use his left foot and the rail to get up and down the Stairs and if he tries to stand up on his right leg and foot they shake flop over and he falls down he also wears nike free run 4.0 v3 and the right one. Smells but the left doesn't and I was wondering if he has duck foot where would it be in his ankle or knee and he has to swing his right leg out to keep his foot from major dragging.
