New Balance developed FuelCell to meet the needs of long-distance runners and offer speed, rebound and energy return. A race-inspired mesh upper keeps things breezy and streamlined, while a gusseted tongue protects from loose dirt and debris. Underfoot, a geometric midsole is wider and higher than its predecessor, while FuelCell foam offers responsive propulsion to your stride, ideal for training runs and races alike. For extra stability longitudinal pods have been added to the outsole, delivering extra grip across a range of terrains. | MFCXLD4
