Certainly interesting idea. The writeup seems odd though.
one: Title is off.
Second: "The shoes sync up with the Google maps smartphone app and vibrate to tell users when and where to turn to reach their destination."
Unless they worked with Google its not possible as out side Google Maps you have no way to notify your shoe about the turn (Through bluetooth).
I'm sure they meant "The shoes sync up with the Google maps SERVICE VIA A smartphone app" and the extra words were probably edited out for brevity. Most people wouldn't understand the difference.
