**Key Elements** & **Research Briefing** & **References** \\ \hline The footwear industry is undergoing a paradigm shift from mass production to mass customization, driven by consumer demand for personalized products. Traditional shoe manufacturers are embracing this trend by integrating modern equipment, methodologies, and information and communication technologies (ICT) into their production processes. ICT plays a crucial role in capturing a wider range of consumer preferences, facilitating the efficient and cost-effective production of customized footwear. & [1] \\ \hline The IDEA-Foot project (2010) proposed a novel integrated design and production methodology. This approach leverages 3D CAD models for production parameter generation and introduces an innovative automated production plant with high manipulator–machine integration, potentially streamlining the process and enhancing efficiency. & [2] \\ \hline To further support the transition towards mass customization in footwear, the IDEA-Foot project (2010) addressed key challenges by developing methods for shoe standardization and establishing a digital data format for transferring geometrical information between design and production. This streamlined data exchange fosters collaboration and empowers mass customization within the footwear industry. & [3] \\ \hline Despite the prevalence of handcrafted methods in fashion footwear, the rise of mass customization and short production runs necessitates exploring automation. However, the intricate nature of the manufacturing process and the paramount importance of quality present significant hurdles to complete automation. The ROBOFOOT consortium aims to develop innovative solutions for automating tasks involving the non-rigid materials characteristic of footwear production. & [4] \\ Product design & The ROBOFOOT project addresses the integration of robotics in footwear manufacturing. It details user requirements, targeted operations, and technical advancements. Notably, the project presents a novel visual servoing solution for precise shoe pose identification. This technology facilitates the seamless integration of robots into existing production lines, minimizing disruptions to current footwear manufacturing infrastructure. & [5] \\ Product design & Remanufacturing combats resource depletion and pollution by reviving used products. However, customer demand and fragmented parts pose challenges. This research proposed a new information model for remanufacturing that mathematically analyzes design parameters and uses algorithms to simulate production processes. This can help address design conflicts and optimize the remanufacturing process. & [6] \\ \hline Remanufacturing breushes new life into used products, but to be truly effective, it needs to be considered early in the design phase (DfR). This study explored how to integrate DfR into a company’s strategy using interviews and design management theory. The research revealed that current practices keep these processes separate, limiting remanufacturing’s potential. By aligning strategy and DfR, companies can unlock significant value, potentially benefiting similar organizations as well. & [17] \\ \hline This study examined a new model for optimizing product family design (PFD) used for diverse product lines. It aimed to minimize costs and maximize market share while ensuring reliability for both new and remanufactured products. The model utilizes advanced algorithms to find the best solution, demonstrating its effectiveness through case studies. & [15] \\ \hline \hline \end{tabular}
