Pre-owned, great condition. No OG box. Nike designed this running shoe for short-distance runners. They are engineered specifically for both training and racing distances of 5-10 kilometers. The upper of the ZoomX StreakFly features a streamlined lightweight and breathable engineered mesh upper like the rest of Nike Running’s flagship footwear models. Elevating the shoe are full-length ZoomX cushioning midsoles outfitted with responsive Pebax plate at the midfoot paired with rubber outsoles.
