The Nike Women's Ultrafly Trail layers a Carbon Flyplate between a deep stack of fabric wrapped ZoomX foam for a propulsive, but lightweight feel. The plate is given trail specific make over and works with the shape of the midsole to provide optimal stability and a smooth transition from heel to toe. With a Litebase outsole design and traction lugs, the Vibram Megagrip compound of rubber used in the outsole provides the perfect blend of grip and durability, across a variety of terrain, and in the wet or the dry. Used in the elite running shoes of Nikes range, the Vaporweave upper has also received a trail make over, giving lightweight comfort and reliability, with a classic collar and counter fit system.
