The Nike React Phantom Run Flyknit 2 offers versatility for the everyday runner. Building on the foundation of its predecessor, the shoe expands on its laceless design by adding secure support that feels like it "disappears" on your foot. More foam means better cushioning, keeping you comfortable as you run. Secure Feel The latest in 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 uses 3 forefoot layers. They combine for a lightweight, breathable and durable feel that keeps your foot comfortable. Smooth and Responsive Nike React technology delivers a soft, responsive ride. 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.
