35. Air 180
Year Introduced: 1991
The Air 180 was a mind-boggling feat to youngsters that saw it on the shelves of the local sporting goods store. How in the world did they get the Air bubble to hold on the bottom of the shoe? Not to mention the 180 was very well-respected in the running community. It also was a huge step in the direction of Max Air cushioning technology that would come in other Nike models.
