And, lest you think I exaggerate the impressiveness of this feat, allow me to share a photo of the shoes in question:

Take a moment and admire teh sex oozing from the shiny red patent. Allow yourself a moment of awe at the 4.5 inch heel (give or take a quarter inch or so-- incidentally, did you know that there is no industry standard on how to measure heel height? It's true.)
Then, after you've absorbed the color and the heels, glance at the toe. See how pointy? And did you notice that there's not even a platform? That's right. That would be 4.5 inches of heel height.
And I did that for nine hours, with a stress fracture in my big toe. They're really not as painful as they look. (heels, not stress fractures, which are, indeed, quite painful)
My only quibble is how far towards the instep the heel is set. It really shifted my center of balance and I had a hard time getting used to it.
Today, red stilettos.
Tomorrow, the world. *maniacal laugh*
