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. The redesigned upper and 180-degree Air unit come together in an updated execution, outfitted in various colourways including the original 'Ultramarine' that started it all. Benefits:The upper combines synthetic leather and textile for a layered look that's breathable and durable. Nike Air technology absorbs impact for cushioning with every step. Foam midsole creates a cushioned and supportive feel. Rubber on the outsole adds traction and durability.
