NK ACG Mountain Fly Low GTX SE khaki black red white EU 39-45 trail

The NK ACG Mountain Fly Low GTX SE in khaki, black, red, and white is a trail-ready sneaker built for outdoor adventures. Designed for men and women, this low-top version offers a sleek silhouette while maintaining rugged durability. The GORE-TEX membrane provides waterproof protection, keeping your feet dry in wet conditions. The aggressive rubber outsole delivers excellent traction on muddy trails, rocky paths, and slippery surfaces. The ACG (All Conditions Gear) line is known for its functional design, and this model lives up to that reputation.

How to Style It

The trail heritage of the NK ACG Mountain Fly Low GTX SE means athletic pieces - track jackets, mesh shorts - look intentional rather than costume-like.

If you rotate sneakers weekly, the NK ACG Mountain Fly Low GTX SE slots into a three-shoe rotation without clashing with the rest of your closet.
