Nike's Vaporfly 4 puts speed first, as the lightest Vaporfly model yet, the engineered mesh upper provides improved comfort, a consistent fit and a barely there on-foot feeling. Arriving in 'Bright Crimson' with touches of 'Mint Foam' and 'Lime Blast', this design has 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. | HF6412-600
