Nike ACG Ultrafly Trail – Built for Speed and Control on the Trails
The Nike ACG Ultrafly Trail is a high-performance trail shoe designed for runners who want to move fast, confidently, and efficiently across demanding off-road terrain. Engineered for trail racing and long-distance efforts, this shoe blends lightweight responsiveness with stability and elite-level grip, making it ideal for runners chasing speed without sacrificing control.
When running on the trails, the Ultrafly Trail delivers an energetic, propulsive ride thanks to Nike’s ultra-responsive ZoomX foam. This midsole provides exceptional energy return, helping you maintain momentum as the kilometres add up. The foam is unwrapped in the heel for improved responsiveness, creating a smoother, more natural transition through each stride—especially valuable on long climbs and rolling terrain.
A refined full-length carbon fibre plate adds structure and efficiency without feeling overly rigid. Compared to earlier versions, the plate is softer and more flexible, giving you better control on technical trails while still delivering a fast, snappy feel underfoot. This balance makes the Ultrafly Trail suitable not only for racing, but also for long training runs where stability and comfort matter.
The breathable mesh upper is designed with trail conditions in mind. It drains water efficiently after creek crossings or puddles, while remaining lightweight, durable, and secure around the foot. Underfoot, the Vibram® Megagrip outsole provides exceptional traction on both wet and dry surfaces, allowing you to confidently tackle rocky sections, loose gravel, and steep descents.
Whether you’re pushing the pace in a trail race or logging fast long runs on technical terrain, the Nike ACG Ultrafly Trail is built to help you go further, faster, and with total confidence.
