RS-X3 Puzzle Unisex Shoes

PUMA's RS series revives the 1980s high-quality cushioning with RS (Running System) foam, an improved EVA compound offering superior rebound and enhanced stability. Originally developed by the RS Computer, this technology offers excellent energy return and a secure, confident stride, blending vintage aesthetics with advanced performance.
What does the X stand for in RS-X? eXtreme perhaps? eXciting? All of the above? This thrice-eXaggerated form came from a process of stripping away everything from the original RS and building it back up with a stronger mix of materials and a design inspired by puzzles with layers and layers of colours and textures.
