A racing shoe with propulsive power. Inspired by the Vaporfly, the Nike Zoom Fly 3 gives distance runners race-day comfort and durability. The propulsive power of a carbon fiber plate keeps you in the running mile after mile. A full-length Nike React midsole balances cushioning and responsiveness with lightweight, durable foam that delivers an extremely smooth ride. A lightweight upper evokes the look of fast, while the inner sleeve and a low collar conform to your foot in a racing fit. A carbon fiber plate inside the midsole can shrink or expand the amount of fiber layers for maximal flexibility in your stride. An arch band attached to the laces helps take pressure off your instep. The heel tapers away from your ankle to relieve pressure on Achilles tendon. The outsole features rubber on the forefoot and heel for added durability.
