New Balance brings the race day feel of energy return technology to a high performance training shoe. The new FuelCell SuperComp Trainer is designed to look, feel and perform differently. In this execution of the new Energy Arc technology, an arched carbon fiber plate is sandwiched between two layers of FuelCell cushioning, leaving a hollow channel in the middle of the shoe. The plate flattens into the void with each foot strike and returns energy as it reshapes, creating a high-bounce propulsion feel. FuelCell foam provides a propulsive feel to help you get ahead Midsole height 47mm Breathable, flat knit upper with a closed foot feel 'N' logo wraps around the side of the shoe.
