The New Balance FuelCell SuperComp Pacer v2 upgrades to a fully PEBA version of the FuelCell midsole foam, for lighter weight cushioning and incredible energy return, with the height of the foam optimised for the American record holder’s data. A completely deconstructed upper on the Pacer, features a track spike tongue, and a massive amount of large and small holes saving weight and improving breathability. It even has a spray-painted logo to keep the weight as low as possible. Like its predecessor, it uses Energy Arc technology to maximise the power of a plate. Large cut outs through the foam in the underside let the plate flex and pop back to shape with more force, for even more propulsion through your stride.
