This is the Nike Zoom VaporFly 4%, the shoe that crossed the finish line first in Boston yesterday — twice. Nike athletes Geoffrey Kirui, Galen Rupp and Suguru Osako took first, second and third in the men’s elite field, while Edna Kiplagat earned first and Jordan Hasay nabbed third in the women’s race all wearing versions of this shoe.

The Zoom VaporFly 4% pairs a Nike ZoomX midsole (for responsive cushioning) with a full-length carbon plate (intended to minimize energy loss during toe bend without increasing demand for the calf). Together, these features can make runners up to four percent more efficient than Nike’s previous fastest marathon shoe.
