My D actually wore her audition dress, warm or rain coat, and her boots to most of her auditions and would change into her heels (that she packed into her dance bag along with her binder) when her audition time came up, and she left her coat with me

. She wore her boots onto the plane most of the time to keep her carry on luggage as light

as possible.
We saw a lot of girls doing tours on heels and it looked rather painful, especially when you have to cover some distances or at times even have to go outside.
