Now my shoes aren't compatible?

Nike + iPod requires the Nike + iPod Sensor and Receiver Kit, an iPod nano with software version 1.2 or later, Nike+ compatible shoes, and iTunes 6.0.5 or later. To see your workout data on nikeplus.com, you must have an Internet connection and a free Nike.com account. For more information, visit http://www.apple.com/nikeplus/.

By the way, there's a new version of iTunes. I hope it lets me burn CDs again.
