20. Air goes Max.
Sneaker: Nike Air Max
The Air gets bigger. As Nike increased the size of their gas-filled cushioning units, there was a bit of an engineering problem to sort out-namely how to squeeze the Air into a traditional foam midsole. A museum in Paris gave Tinker Hatfield the solution: Why not put the tech on the outside? Carved windows in the foam created "windows" of Air, as well as a whole new category-Air Max. A revolution, if you will.
