Lightweight, responsive foam and a lace-free design make the Nike React Phantom Run Flyknit 2 the ultimate in comfort for the everyday runner. Flyknit technology in the upper adds secure support while Nike React foam in the midsole helps to cushion your every stride. Pops of bright yellow and blue add a touch of vibrant energy to your daily run. Smooth and Responsive Nike React technology delivers a soft, responsive ride. It helps provide support for the 3 phases of a runner's stride—flexibility at toe-off, a smooth ride at mid-stance and cushioning at contact. Secure Feel Flywire technology features an elastic design that intertwines with the Flyknit upper, helping your foot feel secure as you run. Lightweight and Breathable 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.
