Puma RS-0 Winter Inj Toys Sneakers. A mainstay of running culture in the late ‘80s, PUMA’s Running System line gained popularity for its superior cushioning properties. This reissue borrows design cues from the decade that gave birth to the original and throws in some modern updates for good measure. Provides immediate support in a lightweight package, while a textile upper allows air to circulate and suede overlays add a soft visual accent. The elastic sock construction provides extra comfort, and the rubber outsole ensures solid grip.
