How long after you start ballet can you dance Demi pointe?
If you are talking about demi pointe shoes (otherwise known at
soft blocks) your teacher may recommend you to wear them. I
recently got my demi pointe shoes and have been taking ballet
classes for just over a year (now at grade 4). Mine were very
uncomfortable at first, but you just have to break them in, just
like you would for a regular pointe shoe. If in any doubt talk to
you ballet teacher, they could give you some advice about whether
you should need soft blocks.
Also if you are taking RAD intermediate exams, I believe it is
compulsory to have demi pointe shoes. Not completely sure though, i
would double check.
Good luck and hope this was some help to you:)
