The experiment was designed to highlight its new advertising platform called Art, Copy and Code.
Google took a few pairs of Adidas sneakers and crammed in a small computer, an accelerometer, a pressure sensor, a gyroscope, speaker and Bluetooth.
The shoe can tell what you are or aren't doing and can then relay that information to your phone via Bluetooth or to you via the speaker in the top tongue of the shoe.
Aman Govil, lead of the advertising arts team, told ABC News that the 'Talking shoe' is an experiment in how one can use connected objects to tell stories on the Web.
If one puts what the shoe knows through an algorithmic logic engine, it can translate it into copy, Govil explained.
Now if that copy is given to an interesting copy writer, one could give the shoe personality. One shoe could be the trash-talking shoe, he added.
