3D printed shoes are footwear created using additive manufacturing technology, which builds objects layer by layer from digital designs. This process allows for precise customization, enabling shoes to be tailored to individual foot shapes and preferences. The materials used in 3D printing, such as thermoplastics and flexible filaments, provide durability and comfort. Brands like Nike and Adidas have started exploring this technology, offering innovative designs that can enhance performance and reduce waste in production.
