Ah, the future! Where did it go? Weren't we supposed to have jetpacks by now?
They might not be as good as a Marty McFly hoverboard, but these motorised shoes are still pretty nifty. Developed by American company Treadways, they're intended to get you from the house to the train, or the train to the tube, or the tube to your bike, without needing to be taken off when you get there.
(Treadways are from Los Angeles, so I don't know where they've get this concept of public transport from.)
They're not quite there yet, but they already look pretty fun to run around on...
