Nike ACG Ultrafly Trail Black and Dark Smoke Grey

Discover the Nike ACG Ultrafly Trail in the Black and Dark Smoke Grey colorway, the spearhead of the ACG relaunch in 2026. After consolidating Nike Trail under the All Conditions Gear banner, the brand is repositioning its outdoor line as a standalone entity dedicated to off-road performance — and the Ultrafly Trail is its showcase.

This 2026 version takes the foundations of its predecessor and pushes them further. The extra-thick ZoomX foam midsole — improved over the first generation — is paired with a carbon fiber plate that is more flexible along its entire length, delivering responsiveness and cushioning without the stiffness of earlier versions. All of it rests on an aggressive, lightweight Vibram outsole, designed to grip unstable terrain while shedding debris. The whole package is also lighter than the original.

The upper in breathable mesh with integrated drainage is traced with wavy patterns that give the pair its characteristic “wavy” look. The Black and Dark Smoke Grey colorway dominates the upper with structural overlays, while touches of Barely Volt appear on the sole and outsole for visibility. The ACG logo and the oversized Swoosh that blends into the tooling sign off the whole.

Designed for long distances on the trail, it combines the best of Nike's fast road DNA with the toughness demanded by trail running.
