Nike conducted development over four years with programmers, engineers and designers to ultimately develop the technology needed to create an upper with static properties for structural strength and durability. The precise placement of support, flexibility and breathability - in a single layer - was then refined. The end result was a featherweight and virtually seamless upper with a perfect fit.
