Future Ballerinas ?

was surfing the net and i came across all these sky-high platforms
gosh they are like sooooooooooo HIGH
man i really salute those fashionistas who're daring to give THESE a try
so every girl's gonna be a ballerina in the coming future ?
i just wonder how can they balance themselves =X
even super models can trip in their extreme stilettos
