Nike Air technology’s original models include the Nike Air Max 1, Nike Air Max 90, Nike Air Max 95, and Nike Air Max 97, which were all intended for running and performance. However, the newer versions of the design, including the Nike Air Max 270, Nike Air Max 720, and Nike Air Max 2090, which all feature a large bubble cushion, have been mostly made for casual wear rather than with a focus on performance. Nike continues to produce the latest and newer Nike Air Max models with lifestyle and casual wear in mind, whereas with older Nike Air Max models, focus is mostly on collabs, special editions, and unique colorways.
