Inspired by the Vaporfly, the Nike Zoom Fly 3 gives distance runners race-day comfort and durability. The power of a carbon fiber plate keeps you in the running mile after mile. The full-length Nike React midsole balances cushioning and responsiveness with lightweight, durable foam that delivers an extremely smooth ride. The lightweight upper evokes the look of fast, while the inner sleeve and a low collar conform to your foot in a racing fit. The arch band attached to the laces helps take the pressure off your instep.
