The RS-X Reinvention' Irish Green' rethinks old-school Puma technology, with a bold mesh, nubuck and synthetic upper in a vibrant color-block style. The silhouette is primarily white, with green and black taking on the overlays. The barely perceptible Formstrip comes in the form of side stitching, with more branding on the tongue and rear panel. An exaggerated heel counter combines with the chunky midsole to further the heritage aesthetic.
