Diversion

Because of the image that struck me yesterday can't seem to get off my mind, I've been on youtube the whole day.

And there's always a question that I've wanted to ask: How do these Japanese and Korean girl groups dance with their heels on?

Take for example of this Japanese group Perfume.






and then this Korean group Girls Generation







Like with their swift moves how can they balance themselves? And their feet seem not to hurt? Stilettos are just deadly to dance with.
