Nike paired up with Apple to produce, what I think, is a great piece of running kit to encourage you to get out and about, walking or running.
What is the Nike+ Sensor for?
The Nike+ sensor and iPhone app track your running progress while you’re out and about through distance, speed and calories. It’s a little like the stats given to you while running on a treadmill. It’s great to have those milestones to help you keep going, even while listening to music. The app gives you stats to take away and feel good about.
