From wisebrother.com:
"A tech startup in Pittsburgh called Shift Robotics is trending thanks to their new BATTER-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.
You can't drift in them. So they're not like skates, or those "Heely" shoes with wheels that kids wear. The wheels stay locked unless you're walking. So you can go up and down stairs in them. And there's a feature to limit your top speed when you're walking downhill.
The downsides are they strap to your shoes, so they're kind of bulky. (And ugly.) And the price tag will be around $1,400. (!!!)
They're available for pre-order on Kickstarter for a little less than that right now and ship in March."
