SAN JOSE, Calif. -- Nike Inc. and Apple Computer Inc. have teamed up to try to become a runner's best friend.
The two companies said yesterday they are jointly developing a wireless system so some Nike shoes embedded with a sensor can communicate with Apple's iPod Nano music player to track a runner's performance and help choreograph songs to the moment.
The Nike+iPod Sport Kit, which will be available in two months at $29, has already won an endorsement from Tour de France champion Lance Armstrong, who plans to run his first New York marathon later this year.
``It will take working out to a whole other level," said Armstrong, who appeared at the companies' news conference in New York City.
The co-branded kit comes with a sensor that fits inside compatible Nike footwear -- sold separately -- and a wireless receiver that attaches to the iPod.
Data on running time, distance, pace, and calories burned would be stored on the iPod, which could then display the information on-screen or deliver it audibly through headphones.
After the workout, the data also could be automatically sent to a personal runner's log at the new nikeplus.com website whenever the music player is synchronized to Apple's iTunes.
The iPod will also incorporate a new ``Power Song" feature, so a user can instantly queue up a piece of music for extra motivation at the push of a button.
The $100 Nike+ Air Zoom Moire shoe will be the first footwear designed to talk to the iPod, and more are planned, said Trevor Edwards, Nike's vice president of global brand management.
