The PUMA RS-X3 ‘Puzzle’ applies a neutral color scheme to the silhouette’s distinctively layered build. The upper features a grey mesh base with Off-White suede overlays, black no-sew skins and a grey leather Formstrip with zigzag stitch detailing. The wavy lines up top are complemented by a white foam midsole with angular TPU pieces on the lateral sidewall. RS-X branding adorns the stitched-on tongue tag, which doubles as a pull tab for easy entry.
