Nike ACG Ultrafly

A result of more than 30,000 miles of testing, the Nike ACG Ultrafly Trail Running Shoes are ready to take you to new heights on the trails. Nike has proven the ability to develop championship winning road running shoes. The learnings from this have carried across to the world of trail running. With a ZoomX midsole, carbon-fibre FlyPlate and Vibram® Megagrip outsole, the Nike ACG Ultrafly Trail Running Shoes offer incredible levels of performance. The ACG Ultrafly features a midsole composed of ZoomX foam – Nike's lightest, softest, and most responsive foam. The super foam has been left exposed, as this allows the material to morph and respond to uneven terrain. Not only should the midsole propel you forward, it should help you save energy over the course of a run. Making them a particularly good option for ultra distance events, when you’re trying to push the pace for many hours. There's also a ZoomX sock liner to further enhance underfoot comfort. A redesigned carbon-fibre FlyPlate is less rigid than the first edition. It also has a spine split so that it can flex with difficult terrain. The plate still delivers lots of propulsion to help you run further and faster. Vibram® Megagrip delivers traction on a wide range of surfaces. It should help you feel confident on both wet and dry terrain. If you’re looking to run personal bests in trail races and stand on the top step of the podium, the Nike ACG Ultrafly Trail Running Shoes are ready for the challenge.
