You probably think I find these clips funny as per my previous post, the fact of the matter is, I don't. I just feel sorry for these models. I cringe every time I see them trip or fall. Set designers ought to work on the stages and make them safer for the models. And it's not just the runways that are problematic, just look at some of those ridiculous shoes.

Is that a cross between treacherous and lecherous?
I would blame malnutrition for making them lightheaded. You need a hard surface to walk on, because of the nature of those shoes. If they walked on a rubber surface, it would be even more difficult.
