The midsole is made of full-length ZoomX foam, Nike’s lightest and most resilient foam, delivering a high level of energy return with every stride you take. Four permanent spikes help reduce the weight of the plate and creates a wide, flat platform for a stable connection to the track. New yarns and a new engineered upper structure enhance breathability and comfort. The conforming fit of the upper gives a disappearing sensation that is built to go the distance. We reinforced the heel to help improve overall stability. Carbon fiber on the midsole unlocks plate response and helps reduce weight. The curved design gives you a propulsive feel. Our most dominant distance track spikes are back at the starting line, raring to break even more world records. Now loaded with an ultralight ZoomX foam and a responsive carbon fiber plate, the Dragonfly 2 Elite can help unleash a new level of speed you’ll want to save for race day. Donned by the fastest 5K and 10K runners in the sport, ready to reach new heights.
