While the theatrics are fun to watch and appreciate, I do not think these types of shoes have a place anywhere BUT on the catwalk (unless you are Victoria Beckham that is).
Even though I do like the shoes (especially the last ones here), I only like them to look at and not to wear. I feel that a jagged heel disrupts the streamline and elongated leg that a heel is meant to create. During the Spring 2009 show I found myself looking at the shoes trying to figure out what was on the heel rather than paying closer attention to the clothing. For myself I think they only belong in the magical environment of runway and not everyday life. But they are fabulous nonetheless!
