Abstract :
In this research, the anomaly of flatfoot was initially introduced, followed by an examination of both traditional and new methods for designing and manufacturing orthotic insoles suitable for it. Regarding this matter, the design and construction of orthotic insoles using a stamp as a traditional method was introduced, and subsequently, the step-by-step elucidation of new methods, including foot scanning and the utilization of smart orthotic insoles in designing and manufacturing insoles suitable for flatfoot, was carried out. In both of these new methods, the design and construction of appropriate orthotic insoles involved the transfer of information obtained from the foot to relevant software and their subsequent processing. This research, while explaining the mentioned methods, described how to use engineering design software in designing and manufacturing orthotic insoles suitable for flatfoot. In conclusion, the results obtained from all three manufacturing methods were presented and compared to ascertain the advantages and disadvantages of each approach.
