Built to perform from the gym floor to the turf to the concrete, the New Balance FuelCell Trainer v2 can do it all. A FuelCell foam midsole adds cushioning and a propulsive feel underfoot, so you can stay focused on reaching your workout goals. The lightweight and flexible textile upper has no-sew overlays for a sleek look, with bootie construction and an Ariaprene tongue and gore for impressive foot lock-in.
