Nike ZoomX Dragonfly XC Spikes – Heartbreak Hill Running Company。The Dragonfly is for the cross-country 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. Shoes come Without original Box. Replacement box will be provided. Note: Spikes and tool included. (As shown) Size: 7.5 Men
