Technology Puma NITRO™ ELITE

Information

NITROFOAM™ ELITE is one of PUMA 's best technologies. It is a key ingredient that gives the shoes their exceptional energy-returning properties. This TPU foam is infused with nitrogen, which creates millions of tiny bubbles inside the material, which then provide the necessary cushioning and energy return. The resulting foam is very light, so it is mainly used in racing shoes, where every gram really matters.
