You know those walking conveyer belts in airports? The ones that save passengers the panic of running through an airport, only to arrive at a terminal ten seconds too late? Yes, we all wish city planners would put them on sidewalks by now. Alas, they don’t seem to hear our pleas, but some inventors from Geneva have decided to take speed walking into their own hands. They’ve developed the first-ever electronic “under shoes,” called Rollkers. Apparently, anyone wearing a set of these can travel up to seven miles per hour faster, and the company claims that, unlike typical rollerskates, no training is necessary. Great idea, let’s just hope bag snatchers don’t catch on.
