NEW BALANCE FUELCELL PRISM

The Prism is defined by its co-molded medial post—a firmer wedge of foam on the inner side of the shoe. Unlike old-school stability shoes that use hard plastic "plates," the Prism uses foam density to gently guide your foot. In 2026, it is highly rated by runners who only need "light" stability; it provides just enough security to prevent overpronation during the final miles of a long run without feeling stiff or intrusive.
