Is a 9.5 year old girl with ballet lessons for the past 4 years, ready to use the ballet pointe shoes?

Probably not. Of course it does not depend so much on the age as to how strong and pulled up they are on releve. Does the back look straight, is their bottom under, are the knees straight are the feet all the way on releve or half way up, are the legs turned out with out swaying the back or teetering to much. Also, another important question is if she has stopped growing or not. Feet are very malleable at this age and you don’t want her to be crippled, this will not help a future ballet career but hurt it in the long run.

I’ve never seen a nine year old ready for pointe.
The best ages are between 11 and 14 for most, with 11 being rare. Even then the training in the shoes may be limited to
de-shanked shoes for a year.
