Overall a super high quality track spike. I had the Dragonfly XC’s before and these are a huge step up. I almost forgot I was wearing them because they are so light. Speed wise they feel amazing, they can handle 200 repeats or a 2 mile race. They make both feel smooth and efficient, really loving getting to wear them so far. The Carbon plate paired with ZoomX makes a deadly combo, definitely the best spikes on the market.
