Susan. Only if the foot isn't built right at birth, and if the shoes are not a good fit. I suppose you are aware that a hopefull candidate for a Ballet company has to have a thorough examination to see if there might be future problems with their build and structure. Many are disapointed. But then what would be the use of accepting somebody who is going to have problems later. I believe that if the bones of the feet are't as they should be depending on the work load, foot trouble is inevitable.
