what's your poison?

girls, shoes, and obsession seem to be an inescapable combination. the girl wearing these marc jacobs mouse flats said she had fifteen different pairs... fifteen! what is it about shoes that make us totally lose all sense of reality? flats, stilettos, wedges, sneakers, boots, clogs and everything else in between... they have the power to make some of us go totally bonkers.
so, what's your poison - a particular sort of shoe or something else entirely?
