The Nike Air Zoom Structure 18 running shoe features added firmer foam for increased stability, along with ultra-responsive and high-speed cushioning to go faster for longer. It improves upon its predecessor with a triple density Dynamic Support Midsole. A new firmer foam along the heel and medial midfoot helps reduce excessive pronation while the Dynamic Support technology uses lightweight wedged foam to support your foot, dramatically increasing stability without adding weight. The full mesh inner sleeve provides enhanced breathability and asymmetrical Dynamic Flywire wraps the midfoot to create a glove-like fit.
