I have a weakness for oversized details on shoes. They lend an air of whimsy to the most basic of shoe silhouettes and add another dimension of interest to what can otherwise be a boring shoe. Fendi apparently has the same sort of weakness, because their recent flats all have some sort of hardware or interesting detail on the toes. Their black patent leather flat with a large buckle at the toe is lovely: it's classic enough to last through many years, versatile enough to wear with almost anything, and just plain polished. The Fendi version retails for $368 on Bluefly (I spend far too much time on that website).
But if that's a bit out of your price range, Payless has its own version (below) for $19.99.
Hmm now that I look at the photos side-by-side, the resemblance is uncanny.
