A refined take on the original Ultrafly, built for going fast and far over trail. Nike reworked the foam, plate and outsole to cut weight while keeping grip on wet and loose ground - tuned for racing and long runs across mellow to highly technical terrain.
- ZoomX midsole for high energy return with a stable ride - the heel foam is left unwrapped for extra responsiveness
- Full-length carbon fiber plate - softer than the original Ultrafly for more control on technical trail
- Breathable mesh upper - light and durable and drains water
- Vibram Megagrip outsole for durable traction on wet terrain
- Approx. 287g | 10.1oz (Men's US 10) - 8.5mm heel-to-toe drop
- Colorway: Racer Blue | Vivid Purple | Purple Dynasty (HF5668-401)
