Description
The Nike ACG Ultrafly is built for speed on technical terrain—light, responsive, and ready for race-day pressure. Part of the Nike ACG collection, this shoe blends elite-level cushioning with rugged trail control so you can push pace without losing stability.
A breathable, reinforced upper keeps weight low while protecting against debris. Underfoot, responsive foam (often paired with a plate setup) delivers propulsion and efficiency, helping you move faster over long distances. The aggressive outsole grips hard on rocks, dirt, and loose trails, giving you confidence at speed.
Fast on trails isn’t easy—this makes it feel easier.
