A tech startup in Pittsburgh called Shift Robotics is trending thanks to their new battery powered shoes that make you walk up to 250% faster. They’re called Shift Moonwalkers and kind of look like roller skates. But they’re designed to let you walk like normal. Basically, you’re walking and rolling at the same time, which sounds tough. But they use A.I. to adapt to the way you walk, so you don’t trip or fall. The price tag will be around $1,400.
