The Nike ACG Mountain Fly Low ‘Brown Basalt’ features a classic outdoor palette that combines rich earth tones with subtle pops of color. The seamless upper is crafted from brown ripstop nylon with contrasting purple accents on the tongue tag and translucent heel patch, both marked with ACG branding. Webbing straps integrated into the reflective rope laces provide an extra-secure fit, while synthetic overlays at the forefoot and heel deliver enhanced durability. The lightweight build is mounted on a Nike React midsole with a full-length carbon fiber for improved energy return. A rubber outsole with outdoor lugs yields grippy traction on multiple surfaces.
