The project was designed to be inspired by the unique structure and repeated circular shapes of the citrus fruits. This high-heel design is a modular shoe that does not require glue use and sewing and can be separated and discharged 100%. Since this shoe does not use glue, it was tried to solve the health deterioration of production workers caused by using glue and change the non-recyclable state that occurs when disposing of them by breaking the mixed form of various materials. In addition, the design was devised as a shoe that can be worn for a long time by paying attention to sustainability
