The Nike Epic Phantom React Flyknit 'Hydrogen Blue' came out in May 2019 with a sky-inspired colorway meant for summer. Dual pull loops offer easy changing, and the glove-like fit wraps the foot in snug comfort. A Flyknit upper features tough, engineered yarns on the sides to provide lateral stability without sacrificing range of motion. For more support, a clip in back envelopes the heel, while pressure-mapped React foam delivers a soft, responsive ride.
