Low cost British airline easyJet unveiled Sneakairs, smart sneakers which
relay directions to whomever is wearing them. Connected to a mobile phone via
bluetooth, the Sneakairs vibrate in the shoe corresponding to the correct
direction to head towards.

The Sneakairs are embedded with GPS sensors that connect to your mobile phone
via Bluetooth and the easyJet mobile app. Once you input your destination
into the easyJet app, the shoes will set off a variety of  vibrations to let
you know which direction to turn, whether or not if you are off course, or if
you have reached your destination. The easyJet app's navigation tools are
powered by Google Maps and Google Map Directions API.
