Received: 26 August 2023 Accepted: 1 November 2023 Published: 30 November 2023 Abstract: Sneakers have evolved into a new fashion style popular among Generation Z, including in Indonesia. The massive use of social media has increased the sense of individualism for everyone in expressing themselves. It is one factor that supports the development of the Mass Customization Business Model. In manufacturing custom products, 3D Printing is a technology that has the advantage of producing short serial and personalized products. This study explores sneaker designs that can be customized in certain parts using 3D printing technology. We conducted existing studies and expert interviews to determine sneaker features that can be customized with 3D Printing. In this research, some experiments were also executed to determine the 3D printing material and lattice structure that are more appropriate and applicable. This research results in the application of 3D Printing on the sole and accessories that can be customized on the lace and heel. Based on consumer analysis, the more popular sneakers are unisex characters. Meanwhile, the results of observing fashion trends are the significant impact of the COVID-19 pandemic, depicted through two design concepts: Hygen (Hygienic Expression) and Radex (Radical Expression). On the basis of a series of research and experiments that have been carried out, the sneakers that Generation Z will favor are sneakers with cosmetic features that can be customized to meet individual expressions.

Introduction Sneakers have evolved from basketball sports shoes to a new fashion style (Williams & Heo, 2023). Especially in the younger generation, sneakers are combined with formal suits, which have never been seen before (Keyser, 2015). Generation Z, who are also known as digital natives, are accustomed to using gadgets, the internet, and online social media. According to Beaver (2012), the massive use of online social media has resulted in an increased sense of individualism for everyone in expressing themselves.
