While not much information is known, Apple retail stores are apparently in some form of tie-in with Nike to promote its NIKE iD service. A note on Apple’s Web site reads: “Express yourself, define who you are, be creative and make a statement. What do your shoes say about you? That you’re a fan of USC? That you adore the color pink? With NIKE iD, you can personalize your shoes to represent you. Visit an Apple Store and ask a Mac Specialist for more details about NIKE iD.”
