With a lightweight, breathable upper and cushioned midsole, this adaptable spike dials you in for a wide range of middle- and long-distance races. It takes learnings from the game-changing Dragonfly spike to give you efficient energy return for the tough middle laps and top-end speed as you kick into the homestretch. Added cushioning at the midfoot and heel give you the comfort needed for longer distances and a smooth, propulsive transition for your footstrike. Single-layer mesh provides lightweight breathability in areas needed most without sacrificing proper containment. Four replaceable spikes offer optimal traction on all track surfaces. Lightweight ceramic aluminum material provides durability.
