Imagine if you could explore Europe's greatest cities without having to constantly look down at your phone to make sure you're on course to your next destination.
U.K.-based regional airline easyJet is trying to solve that problem, at least in theory, with a new pair of internet-connected sneakers that signal to wearers when to turn left or right by vibrating underneath the respective foot. This way, sightseers' heads can stay up, taking in the surroundings while they walk, without losing their way.
