The women’s Nike React Phantom Run Flyknit 2 ‘Vast Grey Orange’ makes use of a Flyknit upper with a sock-like collar for a snug fit around the ankle. The slip-on silhouette adds elastic Flywire cables for midfoot containment, while the forefoot features three-layer knit construction for enhanced durability and support. The two-tone color scheme up top is offset by a crisp white React foam midsole, good for lightweight and responsive cushioning.
