Jakob Ingebrigtsen'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 the Norwegian runner's favourite neutral shades, this special design also features the Nordic stars on the insoles. 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. HV6107-100, Textile & Synthetic Upper/Synthetic Sole.
