Nike and Apple will officially release the Nike+iPod Sports Kit on Thursday, July 13. The Nike+iPod Sports Kit was announced in late May and features a small transmitter which, when placed in a special compartment unique to Nike+ shoes, records and wireless transmits running information. This information transmitted by the shoe can be later reviewed with iTunes. So far, this kit only works with the flash-based iPod nano player, not the large iPod with video or smaller iPod shuffle. The Kit costs $30 while the new shoes will cost between $80-100 at retailers. To use the Nike+iPod Kit users require iTunes 6.0.5 or later is required on a Mac or PC.
