Technology: Visible Air

If you were going to go through all the trouble of putting Air (actually an inert gas) in a shoe, why hide it away behind boring foam? Visible Air was more a matter of evolution than anything; as the Air bag grew bigger and bigger, there was nowhere else for it to go. The window in the sides of the Air Max just grew and grew, with 360 Air being the ultimate result.
