that is not typically a problem with the foot itself, but more than likely is related to the shoulder. Calves can come out of being over in the knee and up on the toes. but I have not seen them come out of toeing out as it his a result of being too straight in their should and the animals method of compensating for that structural flaw. if you can change the skeleton, you can change the feet. I never had any luck with that. is he a bit high in his spine as well? very often that is another compesation for the straight shoulder.
