The Wmns Epic Phantom React Flyknit 'Hydrogen Blue' was released May 2019 in an icy colorway meant for summer running. For easy on-and-off, dual pull loops and a slip-on fit deliver hassle-free function, while lightweight and flexible Flyknit fabric wraps the foot with a glove-like feel. Non-elastic, engineered yarns provide side-to-side stability without trading in the sneaker's full range of motion. Pressure-mapped React foam delivers a soft, responsive ride.
