About the Nike ACG Ultrafly Trail
The ACG Ultrafly Trail is Nike's trail racing shoe, an updated version of the original Ultrafly built for speed over long, technical routes. A ZoomX foam midsole, left exposed at the heel to free up more of the foam's bounce, sits over a full-length carbon fiber plate that Nike tuned softer than the first model's for better control on uneven ground. The mesh upper is lightweight, durable, and made to drain water after stream crossings, while a Vibram Megagrip outsole grips wet rock and mud. Nike lists the weight at roughly 287 grams in a men's size 10, with an 8.5 millimeter heel-to-toe drop.
Within Nike's outdoor range it sits at the race-day end of the lineup, aimed at runners who want a plated, high-energy platform away from the road.
