New Balance FuelCell SuperComp MD-X v3

The SC MD-X v3 is a masterclass in track engineering, featuring a 100% PEBA FuelCell midsole for elite energy displacement. The bottom-loaded carbon fiber plate provides a rigid lever for explosive propulsion, while the 20mm stack height ensures compliance with World Athletics regulations. In a significant update, New Balance introduces a removable six-pin system, allowing for surface-specific customization. The single-layer engineered upper provides a high-tension, anatomical lockdown. For the serious athlete, this spike offers the mechanical advantage required to shave seconds off personal bests, from 800m to 5000m.
