Max Air, Nike's best-known technology, was introduced back in 1987 as an update to the standard Air that it had been cushioning sneakers with since the late '70s. Zoom Air, a lower-profile and more responsive take on Air, made its debut in 1995. More recently, Lunar foam was introduced for the 2008 Olympics.
Together, these roughly 30-, 20-, and 10-year-old\u200b cushionings can be found on the majority of Nike's performance footwear today. They've all gone through multiple iterations and tweaks, but the underlying concepts have remained the same.
That's not necessarily a bad thing, as these technologies each have their fans. That longevity doesn't necessarily imply that they're no longer relevant. But it's easy to see why a brand that prides itself on innovation would want to offer something new in terms of cushioning when we live in a world where you need an app to cop hyped sneakers via geo-tagged locations. (Not to mention a world where Adidas' Boost is handily beating it in the hyped cushioning game.)
Enter Nike's new \u201ccushioning revolution,\u201d which includes the highly visible VaporMax (an Air-based cushioning), ZoomX, and React\u2014the latter two of which are foam-based technologies ...
