It 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. FlyKnit Loft is the latest update to the popular material. 3 forefoot layers combine for a lightweight, breathable and durable feel that keeps your foot comfortable. The Nike React Phantom Run Flyknit 2 is all about versatility for the everyday runner. The shoe expands on its laceless design by adding secure comfort that feels like it disappears on your foot. More foam means better cushioning, keeping you comfortable as you run.
