The Nike Zoom Fly, designed with speed in mind, was originally launched in September 2017. The 'Vast Grey' version showcases a versatile Flyknit upper with added structure from fusible yarn, effectively avoiding additional weight. Ensuring a smooth and effortless run, the React foam sole provides optimal cushioning and propulsion, while the carbon fiber plate inside enhances stability throughout each stride. Notably, the oversized Swoosh logo stretches from the ankle to the toe, adding both contrast and promoting brand recognition.
