Nike Vaporfly 4

Powered by Nike’s legendary system of speed: a proprietary combination of ZoomX foam and a carbon fiber Flyplate that helps runners reach their potential, the Vaporfly 4 is the lightest model in the franchise’s storied history, using new athlete insights and Nike’s unparalleled standard of precise design to level up the versatile silhouette that started the super shoe revolution eight years ago.

"The Vaporfly 4 is the ideal Vaporfly. Nike nailed it. There are so many aspects I love about this shoe: It's lighter than its previous iteration, more responsive, gives a comfortable ride, has a stable feel, and offers a great fit. Simply put, it's the perfect combination of carbon to foam in this shoe to date. I love running fast in this shoe."

- Mohammed Ahmed, Nike athlete and Canadian long-distance runner
