I think in the last, say, 3 years, the standard has really dropped. Up until about 2011 you had so many girls who could walk that the ones who couldn't (ahem...looking at you Arizona) weren't so much of an issue because you still had so much quality.
I was watching the Blumarine Spring 2010 video the other day (as I do) and it was just girl after girl working that runway up into an inferno....you had Abbey Lee, Kasia, Yulia K, Jac (who was still considered a newbie might I add), Edita, Vlada, Snejana.......talking top level walkers who knew how to make things come alive.
Now, not only are there so many more new girls but ALOT of them can't walk very well and it's just so evident because they're the ones doing all the shows.
I honestly think that a good, strong walk is not even a prerequisite for alot of these designers, if it was, how the HELL are these girls being cast?
So tired of these bland, sad looking 16 year olds wobbling precariously down the runway it just makes me yearn that much more for the Isabeli's and the Maria Carla's..
I also agree, there are many factors which can make a girl's walk a little shaky (the big/small shoe, the uneven runway surface, the nerves) but I'm sorry, if this is your 3rd or even 2nd season and you still suck, it's you. We can't blame the shoes and the nerves if after 40+ shows you still look as if you're going to collapse into a bundle on the ground.
