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.

This Speed_CELL will calculate top speed, burst speed, total distance traveled, and game-time stats. 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.
