The Nike Ultrafly is a racing shoe for ultra and long-distance runners. It has a sleek mesh upper with a wide toe box, low-volume fit, and secure heel/midfoot. The midsole is ZoomX foam covered by a protective layer of knit fabric. The carbon fibre Flyplate adds a pop unlike any Nike trail running shoe before it. An innovative Vibram outsole brings grip and longevity suitable for technical terrain.

A flat base and minimised cross-rocker provide reliable stability on off-road paths, and the heel-to-toe rocker ensures a smooth ride. Strategically positioned supportive zones in the midfoot give a lightweight and secure feeling under-foot whilst traversing trails at speed.
