About the Nike ACG ZoomX Ultrafly Trail 'Black Photon Dust'

The Nike ACG Ultrafly Trail 'Black Photon Dust' delivers a sleek colorway of a trail-ready runner developed through thirteen rounds of testing spanning 30,000 miles. Wavy lines adorn a black mesh upper that's designed to be lightweight, durable, and breathable. On the lateral side, an oversized Swoosh extends into the ZoomX foam midsole, which is 'unwrapped' in the heel for increased responsiveness. A full-length carbon fiber FlyPlate delivers energy return and a smooth, efficient transition. Underfoot, the Vibram Megagrip outsole provides reliable grip on rugged terrain.
