[CES 2015] Rollkers intends to change the way you walk – in fact, walk twice as fast. This is an add-on, so to speak, to your pair of shoes, pretty much in the same way Montblanc has a way to tack on something to your watch so that it can become a smartwatch. The Rollkers has been touted to be an ideal personal transit accessory which is said to be able to increase one’s walking rate up to 7 miles an hour – how about that?
