Nike W Zoom Fly 3 (Dark Smoke Grey/Pewter)

A RACING SHOE WITH POWER.
Inspired by the Vaporfly, the Nike Zoom Fly 3 gives distance runners race-day comfort and durability. The power of a carbon fiber plate and responsive cushioning keeps you in the running mile after mile.

Full-Length Cushioning
A full-length Nike React midsole balances cushioning and responsiveness with lightweight, durable foam that delivers an extremely smooth ride.
The Look and Feel of Fast
A transparent upper evokes the look of fast, while the inner sleeve and a low collar conform to your foot in a racing fit.
Propulsive Feel
A carbon fiber plate inside the midsole can shrink or expand for maximal flexibility in your stride.
