I've not seen these but they look interesting. I love my Birkies but the next time my #2 loudly calls them elf shoes in the middle of the market I'm liable to stick them somewhere, which she knows, so she will. I'd get a pair just to clock a look on her face, and if they're good, all the better.
So the professional has big holes in the side of them which doesn't look so much fun but the endeavor looks like the same deal sans holes. Are these over the web purchases only or are they retailed somewhere?
