The future will be faster. The Puma x Ader Error "RS 9.8" is inspired by new frontiers and galaxies, by individuals who defy societal rules and the laws of physics. The name RS 9.8 speaks for 9.8 m/s2, which corresponds to the approximate speed of gravity near the Earth's surface. This forward-looking retro design combines elements from various models in the RS family, including super comfortable insoles and RS foam, and reinvents the midsole to create space-inspired spheres. Here in the strictly limited Ader Error Edition.
