Potential
Designer Marc Jacobs has brought a whole new meaning to walking on your toes with the release of the world's first back to front heel. "A chunky, four-inch heel nestles horizontally just under the ball of the foot," Spluch.com clues us in. "Where you'd expect a heel, there is nothing but fresh air. The centre of gravity therefore is somewhere under the arch of the foot, forcing the whole body to tilt forward."

Implications - As part of the 2008 collection from acclaimed fashion designer Marc Jacobs, users will be given the opportunity to wear both plain and high-priced Swarovski crystal shoes.
