Nike + iPod– Meet your new personal trainer.
Grab your iPod nano, iPod touch or iPhone 3GS, a pair of Nike+ shoes, and the Nike + iPod Sport Kit or Sensor. Put the sensor in your Nike+ shoe — there’s a built-in pocket specifically designed for it under the insole. Then connect the receiver to your iPod nano.
iPod touch includes built-in support for Nike+, so no receiver is necessary. The sensor tracks your run, then sends the data to your iPod.
