Rollasole has come up with a brilliant product: cute metallic ballet flats that roll up. In the UK, they're being sold in vending machines at clubs, which is genius. Just think of all the times you wanted to take off your stilettos, but didn't want to go barefoot. These are fashionable, cheap (about $8), and compact.
The shoes haven't made it over here yet, but you can buy 'em online here. So cute, no?
