Nike Dragonfly 2 One of the fastest long-distance track spikes to ever cross the finish line turns up the tempo even more. The Dragonfly 2’s comfortable fit and propulsive feel are built to go the distance in races and key workouts. Updated spikes, full-length ZoomXfoam and a lighter, more responsive plate are ready for speed, stamina and podiums. Stable for StraightawaysA slightly wider midfoot and forefoot compared to the previous iteration improves the feeling of stability on straightaways and especially around turns. We removed two spikes seen on the original in favor of a four-spike design. And we elevated the big-toe side platform and updated the heel structure for added stability. Light and FastThe new full-length plate material is lighter and more responsive than the previous version while adding durability. The curved design gives you a propulsive feel. Breathable ComfortEngineered mesh on the upper enhances breathability and comfort. Its conforming fit gives you a disappearing sensation that is built to go the distance. Energy Return for Your StridesFull-length ZoomX foam, Nike’s lightest and most resilient foam, provides energy return with each step.
