The latest review notes the Ultrafly Trail’s improved dual ZoomX foam, dual carbon plates, and $260 retail price, with a 9.8 oz weight and 38.1mm heel stack.
Testers praise its plush cushioning, Vibram Megagrip outsole, and stability for ultramarathons, but criticize limited breathability, shallow lugs, and high drop, making it less suitable for technical terrain or hot weather.
