New Balance FuelCell MD-X

The New Balance FuelCell MD-X is a true middle-distance “super spike” built to help you attack the bell lap with confidence and carry speed all the way through the line. Designed for racing from the 800m up through the 5K, it pairs a lively FuelCell midsole with a stiff carbon-fiber plate to create a fast, rolling feel that rewards strong mechanics and quick turnover. Up top, a stripped-down, race-ready upper focuses on secure lockdown and minimal distractions when it’s time to move.
