The Nike+iPod Sport Kit

Nike and Apple have teamed up to integrate the running shoe with the audio player to create a simple yet powerful system for keeping you informed and inspired during your workouts. The kit includes a pedometer that fits inside "Nike+ ready" shoes and wirelessly reports your time, speed, and distance via your . You can opt to have this information appear on your Nano screen; or you can obtain an audible update of your time, distance, and speed by pressing the center select button on your Nano. What I like best about the system is being able to put that special super-psyche-up song in my mix, and select it at the point in my workout where I need an extra blast of adrenaline to complete the final brutal few minutes of my cardio.

To get the whole experience, you'll need to have : an iPod Nano, a computer, a pair of "Nike+ ready" shoes (usually priced at around $100), and maybe an armband to hold the Nano and receiver.
