Porsche said that iconic design elements from the 911 Turbo, such as period-specific paint colours, rear wings, light bars, interiors and body lines, were used as inspiration to create the shoe range. For the collaboration, Puma selected two of its “silhouettes”, or model outlines; the 1970s-inspired Future Rider and the motorsport-inspired Speedcat. These became the basis for two styles reflecting a key evolution in the 911 engine over time: “Air-Cooled” and “Water-Cooled.” Puma also used original Porsche vehicle hues including Riviera Blue, Guards Red, Saffron Yellow Metallic and GT Silver Metallic as an inspiration. The Puma x Porsche collection will only produce 500 pairs per unique sneaker design across all sizes.
