Keep your foot comfortable with the Nike React Phantom Run Flyknit 2 in Black with versatility for the everyday runner. The shoe expands on its laceless design by adding secure comfort that feels like it disappears on your foot. The Nike React technology delivers a soft, smooth, responsive ride that provides support for the 3 phases of a runner's stride—flexibility at toe-off, a smooth ride at mid-stance and cushioning at contact. The latest in Flywire technology features an elastic design that intertwines with the Flyknit upper, helping your foot feel secure as you run.
