Inspired by the vibrant energy and sights that take place during a color run, the Nike React Phantom Run Flyknit 2 brings those electrifying feels to your feet. Building on the foundation of its predecessor, these shoes expand on their 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. Smooth and Responsive Nike React technology delivers an extremely smooth 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. Lightweight and Breathable Flyknit loft uses 3 forefoot layers. They combine for a lightweight, breathable and durable feel that keeps your foot comfortable.
