NIKE ACG ULTRAFLY TRAIL
Nike has officially relaunched ACG (All Conditions Gear) as a dedicated outdoor performance brand centered on trail running, hiking, and mountain exploration.
Engineered to tackle chaos, the Nike ACG Ultrafly strikes back with speed, responsiveness and grip for trail runners who go hard.
Tested over more than 30,000 miles of punishment on the world's most twisted terrain, it's the result of mountains of insight from trail running fiends.
The Ultrafly fuses Nike's fastest road DNA with ACG's dirt-first durability.
- ZoomX Foam Midsole: Next-level energy return. Protection when the ground hits back.
- 7/8 Split Carbon Flyplate: Torsional support. Smooth chaos management.

"It's been my go-to, do-it-all racing shoe", says Nike Athlete Caleb Olson, 2025 Transgrancanaria Classic and Western States Endurance Run winner. "It can handle some of the most rugged terrain I've raced on at Transgrancanaria, as well as the singletrack at Western States.
