This is the adidas miCoach Speed_CELL. This is a very unique little thing. Basically this miCoach device goes into your shoe while you play. Whether it is practice, a game, or just messing around is up to you, but what it does is the amazing thing.

This Speed_CELL will calculate top speed, burst speed, total distance traveled, and game-time stats. I have no clue how it works, but it does and it can really help you improve your game. You can use it to help fine tune your game that way you can be the best player possible. Which is everyone's end goal.

After you are done sync it to your Iphone or Ipod and look at all of your stats. This is something that I believe everyone should get their hands on. It is really cool.
