Introducing the Nike ACG Mountain Fly
The Nike ACG Mountain Fly is a durable, all-terrain sneaker built for outdoor performance, and a key part of Nike’s All Conditions Gear (ACG) line, which has been pioneering technical footwear since the late 1980s.
Designed for both toughness and innovation, the Mountain Fly features a lightweight yet protective upper, reinforced overlays, and a grippy rubber outsole engineered for traction on challenging surfaces. Its responsive cushioning and flexible midsole provide comfort and stability, whether tackling long hikes or navigating urban terrain.
