"The shoe works similarly to a fitness tracking device, using an accelerometer, gyroscope, Bluetooth and other off-the-shelf technologies to analyze the wearer’s movements and offer motivating and timely commentary. It might tell you to get going if you’ve been idle for too long or cheer you on if it senses you being very active. Its comments can be posted to Google+ by the user, sent to real-time ad units, or broadcast via onboard speakers." And the shoe is pretty funny. Watch the video!
