Nike Black Running Shoes

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 gives 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. *Ideal for events like 400m, 10,000m, hurdles, long jump, triple jump, pole vault and cross country *Cushioned insole These are brand new, never been used, NOT in the original box. I purchased these for my son and he tore his ACL and never got a chance to use them. MESSAGE WITH QUESTIONS!!!
