Nike Zoomx Vaporfly Next% 4 Velvet Brown Black

ZoomX is Nike's altered Pebax foam, the lightest and most responsive material the company makes, and the Vaporfly is the shoe built to prove it. When the line launched in 2017 it paired that foam with a full length carbon fibre plate designed to generate extra spring in every step, and peer research found it could improve marathon times by as much as 4.2 percent. Very little in sports equipment has ever been measured that generously. The Next% 4 is the current statement of that idea, and velvet brown over black is an unusual choice for a race shoe: it is a colour from a wardrobe, not from a start line, worn on the most single minded object Nike sells.
