Nike ACG Mountain Fly Low GTX black white grey EU 36-46 trail shoe

The Nike ACG Mountain Fly Low GTX in black, white, and grey is a rugged trail shoe built for unpredictable terrain. Engineered for outdoor enthusiasts, this low-top version of the iconic Mountain Fly delivers exceptional grip and waterproof protection. The GORE-TEX membrane keeps your feet dry during creek crossings and rain showers, while the aggressive rubber outsole offers reliable traction on mud, rock, and loose soil. The ACG (All Conditions Gear) line is known for durability, and this sneaker lives up to that reputation with a reinforced toe cap and abrasion-resistant overlays.

How to Style It

The black, white and grey colorway is built to style easily: straight-leg jeans, cargo pants or shorts all sit well over the silhouette.

One quiet advantage of the black, white and grey palette: scuffs and dirt stay invisible far longer than on white-only releases.

In summer, the Nike ACG Mountain Fly Low GTX pairs naturally with shorts and light chinos; in winter it holds its own under wool coats and flannel.
