New Balance FuelCell SuperComp MD-X v3

Built for the hardest part of the race—the mid-laps surge and the final kick—the New Balance FuelCell SuperComp MD-X v3 is an elite middle-distance spike tuned for speed with enough cushioning to stay efficient when the pace gets gritty. A high-rebound FuelCell midsole pairs with a full-length carbon-fiber plate to create a snappy, rolling feel that rewards quick turnover and strong mechanics. Up top, the airy mesh keeps things light and race-ready, while the spike plate delivers confident grip through curves and accelerations.
