MIT Media Lab researcher Dhairya Dand has invented a smart insole called SuperShoes. Currently in prototype, the silicone insert uses a microcontroller, Bluetooth module, and "vibrotactile ticklers" to connect to your phone and use your GPS to give you directions. Dand says they can learn your habits over time, and suggest routes it thinks you'll enjoy.
