Laceless design and Flywire technology offer a close, secure fit. The Nike Phantom Run 2 offers versatility for the everyday runner. Building on the foundation of its predecessor, it 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 - 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 three forefoot layers. They combine for a lightweight, breathable and durable feel that helps keep your foot comfortable. Smooth and Responsive - Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. More Benefits - Increased rubber at the outsole helps deliver better traction and durability. Molding around the heel helps keep you feeling secure so you can focus on your route.
