The ACG Ultrafly was created for athletes who embrace the outdoors. It's a shoe built to move with the terrain, offering stability, traction, durability, and comfort when the trail gets rough. In the words of Brenden McAleese, Director of Nike ACG Footwear, athletes were directly involved in the shoe's development. "From the beginning, the Nike ACG Ultrafly was developed in lockstep with our Nike athletes who desired a trail tuned super shoe," McAleese said in the press release.
Nike packed the ACG Ultrafly with the most advanced footwear technology, tailoring it to meet the specific needs of athletes at every level who enjoy the outdoors. The shoe features Nike's ZoomX foam, a ZoomX sock liner, and a carbon fibre FlyPlate. The ZoomX midsole is Nike’s lightest, softest, and most responsive foam, and it gives you back 85% of your energy. In the ACG Ultrafly, the midsole is exposed, allowing it to adapt to the ground beneath you.
