Cleated heels, via Bike Hugger:
I don't wear heels normally, let alone to work out (um, NSFW?), but there's something charmingly ridiculous about these shoes. I can't tell if they're a joke—I can't find them for sale anywhere. They can't possibly be efficient; your feet aren't secure in the shoes, so they'd fly out with every pedal stroke. In essence, they are candy-colored frippery totally unsuitable for cycling. Still, I love the idea of seeing someone pumping up Pike Street in a pair of pink pumps.
