From the Flymesh upper to the triple-density foam midsole, the Nike Air Zoom Structure 19 Women's Running Shoe offers plenty of support and the response you need for a smooth, stable ride that feels ultra fast. Responsive Cushioning The Nike Zoom Air unit in the forefoot delivers highly responsive, low-profile cushioning to propel your next step forwards—ideal for faster-paced runs. Increased Stability The triple-density Dynamic Support system in the midsole helps slow the rate of pronation with firmer foam along the inside midfoot and wedged foam in the heel, supporting your foot as it transitions through footstrike. Comfortable Support The woven Flymesh upper provides ventilation and support where you need it most, with an added yarn that creates structure without sacrificing breathability. Flat, wide Flywire cables integrate with the laces and wrap your midfoot for enhanced lockdown and a glove-like fit.
