Nike's Vaporfly 4 is the lightest Vaporfly model yet, fitted with engineered mesh that provides improved comfort, a consistent fit and a barely there on-foot feeling. With a higher angle than its predecessor, the carbon-fibre Flyplate is combined with a lower heel-to-toe drop height to offer improved propulsion and speed, while the ZoomX foam weight has been reduced for even more bounce. Grounding the design is a thinner rubber outsole that gives you the same reliable traction with even less weight. | HF6414-600
