Not recommended for beginners. The FuelCell Rebel v5 is a lightweight speed trainer from New Balance, designed for performance-oriented runs. Its FuelCell foam delivers excellent energy return, but the 40mm/34mm stack prioritizes speed response over plush comfort. While the carbon-plate-free design provides a natural, flexible feel, it requires adequate leg strength and proper running form to be used effectively. Beginners running at slower paces will find the midsole feels firm and lacks the forgiving cushioning needed during the early stages of running. For those new to running, the 880 or 1080 series are far better options — they offer softer cushioning, greater stability, and a more forgiving ride that helps reduce injury risk while building consistent running habits and enjoying the sport.
