Nike’s pitch: Delivers speed and responsiveness to every run. Gentle used, Size 8.5. ( the tag that reads sign is gone when I cleaned it, but I am size 8.5 so for sure that’s the size 😉) Upper:Dual-layer mesh, full-length inner sleeve, Flywire lacing. Midsole:React and ZoomX foam with a 10 mm drop. Outsol: Carbon rubber with exposed foam in the midfoot.
