The Dragonfly is for the barrier breakers, the flurry finishers who refuse to give in to the elements. It??s our fastest distance spike on the track built to go off-road, one that recently made its medal-winning presence known on the world stage. ZoomX foam adds a jolt of energy return while a wider base helps give you peace of mind in inclement conditions.

Speed up the Tempo The combination of full-length ZoomX foam and a full-length plate optimizes resiliency and energy return while staying lightweight.

Keep Water Away Known for its lightweight design and low water retention, the partial Vaporweave upper helps keep the shoe light even when wet, and the soft, engineered mesh toe box helps keep your toes and forefoot comfortably contained.

Stay Secure An added arch band helps give you a secure fit in muddy conditions and a supportive feel on uneven terrain.

Wider Base Extra width on the base of the shoe provides extra stability and confidence on all surfaces.
