展开The FuelCell SuperComp Trainer v2 brings the seconds count performance of energy-return technology from race day to a high milage training shoe. In this execution of new Energy Arc technology, a stacked height midsole houses an arched carbon fiber plate, sandwiched between two layers of FuelCell cushioning, leaving a hollow channel through the middle of the shoe. The plate is flattened into the void with each foot strike, and returns energy as it reshapes, creating a high rebound sense of propulsion. The FuelCell SuperComp Trainer v2 is designed to look, feel, and perform differently.
