Apple and Nike are working on a new item of wearable technology that will have greater integration into existing gadgets, and is less obvious and more "stealth," according to Nike chief executive Mark Parker.
Nike has long been making wearable technology, originally partnering with Apple for its Nike+ running sensor range in 2006, which connected wirelessly to the iPod.
Nike discontinued its FuelBand fitness-tracking bracelet in April, shutting down the team that made it, which saw two of its key engineers move to Apple to work on the Apple Watch.
