Per Nike: Harking back to the original mantra of Air Max, the Air Max 90 Ice pushes “making the invisible visible” to the maximum. Taking inspiration from the Ice edition of the Nike+ Fuelband, this version of the Air Max 90 utilizes a translucent outsole to show off the most unsung of cushioning heroes; Phylon. Translucence also appears on the upper in the form of see-through Hyperfuse construction, which allows the computer generated geometric graphic to appear without distraction. The Air Max 90 Ice is Air Max seen like never before.
