In a rapidly evolving global context, the field of footwear design faces an urgent need to re-evaluate its practices in light of pressing environmental challenges and to embrace circularity. This project, focused on footwear design within the framework of the Circular Economy, uses Design Thinking methodologies to integrate Circular Design principles into the development of a specific footwear product, the Circularstep. This initiative highlights the pressing need to re-evaluate available resources, with a strong emphasis on product durability, recycling potential and repairability. The footwear industry faces the growing problem of discarded shoes overwhelming landfills, requiring an immediate shift towards sustainability and circularity. This sector contributes to several adverse environmental impacts, including excessive use of fossil fuels, unsustainable leather sourcing, and the promotion of a disposable footwear culture. To address these challenges, the project aims for a more circular and resource-conscious product. Enraizado no cenário sempre mutável dos desafios de sustentabilidade na indústria do calçado, orientado pela análise de fluxos de materiais circulares e envolvimento significativo das partes interessadas através de uma política de devolução e reeducação dos utilizadores. Quanto ao desenvolvimento do projeto, desenrola-se através da criação e exploração de conceitos, moodboards e fases iterativas de esboços, resultando num produto que incorpora estética e conforto, com um sentido de responsabilidade e compromisso com a economia circular.
