Something's missing

I've noticed a pattern in my recent "OMG, must have!" shoe sightings. It looks like I have a thing for black wedges...of the cut-out/hybrid category. I would buy any of these if I could right now—the beauties in the upper right are from Vagabond, so I'm once again reminded they don't ship to the US....sigh.
