Companies are developing a wireless shoe system.
Nike Inc. and Apple Computer Inc. have joined forces to try to become a runner’s best friend.
The two companies announced last week that they are 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, already has won an endorsement from Tour de France champion Lance Armstrong, who plans to run his first New York marathon 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 will be stored on the iPod, which then can display the information on-screen or deliver it audibly through headphones.
After the workout, the data also can be sent to a personal runner’s log at the new nikeplus.com Web site whenever the music player is synchronized to Apple’s iTunes program.
The iPod also will use a new "Power Song" feature, so a user can instantly queue up a piece of music for extra motivation.
