The first device is based on wireless technology that allows Nike+ footwear to 'talk' with an iPod nano during a workout.
The Nike+ Air Zoom Moire connects to an iPod nano through the Nike+iPod Sport Kit. Information on time, distance, calories burned and pace is stored on the iPod and displayed on the screen.
The kit includes an in-shoe sensor and a receiver that attaches to the iPod, and real-time audio feedback is provided through the headphones.
Nike chief executive Mark Parker and Apple chief executive Steve Jobs unveiled Nike+iPod at an event in New York. "Nike+iPod will change the way people run," said Parker.
"I definitely use music two ways," said Radcliffe. "I listen to faster music if I am doing a workout in the gym to get the best out of myself, but I also use it to help me relax in the build-up to a big race."
Specially designed Nike apparel, including jackets, tops, shorts and an iPod nano armband, feature waterproof pockets that accommodate an iPod nano.
The Nike+iPod Sport Kit is expected to be available for $29. It requires a Nike+ shoe and a iPod nano with a USB 2.0 and Mac OS X version 10.3.9 or later and iTunes 6.0.5, or a Windows PC with a USB 2.0 port and Windows 2000, XP Home or Professional (SP2) and iTunes 6.0.5.
