Air Zoom Structure 18

Created with a triple-density foam midsole, the Air Zoom Structure 18 updates the stability of its predecessor. Adding to the theme of strength is an engineered mesh upper that maintains the breathability of Flyknit while increasing durability. A Zoom Air unit under the forefoot delivers low-profile cushioning with a responsive feel, and the cored-out heel reduces weight for runners looking to cut time. Reinforced rubber at key areas absorbs the shock of repeated impacts.
