The Nike Air Zoom Winflo 7 Photon Dust keeps you running with an updated mesh design and increased stack heights. Designed with longer runs in mind, its cushioned feel helps you focus on the path ahead. Mesh details throughout the upper helps keep the air flowing with every step. Synthetic yarns keep things lightweight, while still providing a secure feel. An updated Air Zoom unit in the heel and forefoot provides cushioning where you need it. The unit in the forefoot is larger in size, giving your foot more engagement with the cushioning for a better underfoot sensation.
