Pointe shoes brands, makes, and models?

First of all, you should not be on pointe if you sickle. You WILL injure yourself! Unless you have really strong feet (not ankles) a soft shank won't be good for you. But overall, you just have to be fitted. Go to a professional fitter and talk to them and your teacher about it. The Perfect Pointe Book, by Lisa Howell, has a lot of exercises to help with common problems and to strengthen all the necessary muscles. As for price, be prepared to spend at least $100. (I'm sorry, I know I didn't really answer what you asked for, but you really shouldn't go en pointe until you are completely ready.)
