Labelled in the '80s as 'RS', which stands for 'Running System', PUMA's highly innovative and cushioned sneakers have morphed into the 'RS-X' with a more robust silhouette, whilst maintaining the retro-inspired silhouette. They're detailed with multicoloured and varyingly textured panels for a playful, eye-catching look. Underneath, a chunky rubber sole offers enhanced comfort and stability.
