The Central Saint Martins x Puma RS-X features collaborative design by the London art school's best students. Part of the "Day Zero" collection, the students' take on the shoe is inspired by the threat of water shortages in the modern-day world. The silhouette gives off a retro '80s vibe with its stark black and white base covered in vivid accents that arrive in purple, yellow, blue, and red. Throughout the upper, you'll see a squiggly neon yellow thread that represents a world map, driving home the message that water shortage is a global issue. A colorful PU midsole is added for cushioning and a rubber outsole brings grip and traction.
