the pointe shoes mould to your feet. if you don't do it properly, yes it can crush your toes.
i have been dancing on my toes for 2 years now and have normal feet.
plus, yes it's painful, but you get used to it.
professionals use new ballet shoes for every show so their feet dont have time to mould and than they get deformed. but at amateur level (like me= grade 7) you dont have freak feet.you have to maintan them though. you can damage your foot if you bend yor knees on a balence or dont cut your toe nails. also if you do it on an uneven surface you can break your ankle.
any other questions?

p.s, we dont wear tutus unless we're in a show.
