Checkout what Google has introduced. It is their talking shoe. Yes, a shoe that actually talks to you and does so to motivate you.

The shoe, which can connect to various servers using the bluetooth technology, tells you if you aren't moving around enough and even encourages you to pick up your pace. Imagine, you are taking it easy and out of no where this voice reminds you to pick up the pace. That voice now comes from your shoe!!

Do you think our ancestors could have ever predicted that one day we would have shoes talking to us??? Much less, have shoes motivating us to move faster or quicker???
