The modular basketball shoe uses seven interchangeable 3D-printed parts, allowing users to repair, customize, and extend its lifespan. Unlike traditional glued shoes that end up as waste, this design reduces environmental impact while adapting to both indoor and outdoor courts. Damaged parts can be replaced with upgraded, data-driven prints, ensuring a better fit over time. By involving users in maintenance, the shoe encourages responsible consumption and redefines how sports footwear can balance performance with sustainability.
