Visible Nike Air cushioning has taken many forms over the last several decades. 1991 brought us 180 degrees of heel Nike Air cushioning for the first time, taking form in the Tinker Hatfield-designed Air 180 runner. Weve seen several reissues since its original introduction, but now the cult classic Air 180 returns in a form closer to the original than weve seen before. The redesigned upper and 180-degree Air unit come together in an updated execution, outfitted in various colorways including the original Ultramarine that started it all.
