Nike ACG Ultrafly 2 – Speed built for demanding trails The Nike ACG Ultrafly 2 is a men’s trail running shoe designed for runners who want to move faster and more efficiently on technical terrain. Ultralight cushioning and improved traction help you build speed with every step on the trail. The Ultrafly 2 refines everything runners loved about the original to help you conquer any distance with confidence. At its core is responsive ZoomX foam , delivering exceptional energy return on varied surfaces. The ZoomX foam is “exposed” in the heel, increasing responsiveness and creating a more dynamic ride. This results in a lively, propulsive feel when pushing the pace on uneven ground. A full-length carbon fiber plate has been tuned to be less stiff than in the original Ultrafly. This adjustment improves control and allows smoother transitions on technical trails. At the same time, the plate supports an efficient toe-off across the entire stride. The lightweight upper is engineered for durability, support, and breathability on demanding trails. It keeps your foot securely in place without adding unnecessary weight. Reliable traction comes from the exclusive Ultrafly outsole featuring Vibram Megagrip . This proven technology enhances grip on wet terrain while maintaining long-lasting durability. With a weight of approximately 287g (men’s size 44) and a 6mm drop, the shoe is built for speed-focused trail performance. Highlights: ZoomX foam delivers maximum responsiveness for fast trail runs. The exposed heel design increases energy return with every stride. The refined carbon plate improves control and smooth transitions. The durable, breathable upper provides secure support on the trail. Vibram Megagrip ensures confident traction in wet and dry conditions. Conclusion: If you are looking for a fast, responsive trail running shoe with reliable grip and a smooth carbon-driven ride, the Nike ACG Ultrafly 2 is built to perform on any distance.Show moreShow less
