ReactX Infinity Run 4 Wolf Grey Black DR2665-002

Speed has a shape, and the Nike 'Wolf Grey Black' (DR2665-002) is built around it. The Flyknit-woven upper in Wolf Grey/Pure Platinum/Cool Grey/Black creates an aerodynamic, foot-hugging fit that minimizes drag and maximizes proprioception — you feel the ground without being punished by it. Lightweight react foam provides the energy return that turns long runs from endurance tests into rhythm sessions. The outsole uses a targeted rubber layout to save weight while maintaining traction at the zones that matter: forefoot push-off and heel contact. Released 2023, this model brings the latest material science to a platform refined by years of athlete feedback. Internal structure supports the midfoot during transitions, and the padded heel collar keeps the fit secure without any slip. The 'Wolf Grey Black' colorway brings race-day energy to a shoe you can train in daily. DR2665-002 — where performance engineering meets everyday wearability.
