They're ankle-threatening, ludicrous, impractical and overpriced. But these shoes will be a huge hit.
It looks like something Salvador Dali would dream up.
Or some sort of reject from the footwear factory.
This is, in fact, the world's first back-to-front shoe, courtesy of designer Marc Jacobs.
Whether you think it is a gimmick too far or a piece of fashion genius depends how far up the fashionista ladder you are - on a scale of one to crazy. Scroll down for more...
Walk this way: The Marc Jacobs back-to-front shoe
Heels have been getting more and more bonkers since the fashion police decreed that kitten heels were over a couple of years ago.
We've had towering platforms, clogs, wedges, block heels and conical stilettos.
But they've all had one thing in common: They were at the back of the shoe.
You know, the area where your heel actually is.
But the Marc Jacobs shoe twist turns conventional fashion ( not to mention orthopaedic) wisdom on its head and places the heel at the front.
A chunky, four-inch heel nestles horizontally just under the ball of the foot. 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. Scroll down for more...
Make or break: Are these shoes the next big thing?
The effort of staying upright in them will be the equivalent of an advanced level Pilates class.
Relax, try to lean back on your heels, and you'll fall backwards.
The must-have accessory to match the shoe then ought to be a crash helmet.
To buy into the trend will cost you £270 for a plain pair and £330 for a more elaborate design decorated with metal swirls and Swarovski crystals.
They are part of the American designer's 2008 collection, which attracted mixed reviews at New York fashion week.
Jacobs himself described his new collection as "the emperor's new clothes" and said it aimed to overturn conventional fashion.
Podiatrists, who already frown on stilettos, are far from impressed.
Lisa Surridge, a lecturer at the Smae Institute specialising in foot health, declared: "These shoes would impair the normal function of the foot."
They are absurd, torturous, dangerous and wearable only by women who never have to walk further than the nearest red carpet and have more money than sense. I give it a week before Victoria Beckham is spotted in them.
