The needs in the sector of orthopedic insoles are becoming more important. The medical purpose of these plantar prostheses is often to correct the posture or biomechanical imbalance that tends to cause pain in various areas of the body depending on the pathology of the patient. This is due to the progression of people who are increasingly obese or have problems with diabetes or other diseases. But, the cost of its products can vary from one to two or more depending on the quality of the product that requires adaptation by a manual process to the morphology of the foot. Whatever the therapeutic product envisaged, the economic model is no longer adapted to the needs of patients and the budgetary imperatives of social security. A new creative process is needed and must incorporate digital tools to reduce these manufacturing costs while improving the quality of products. This study is the continuity of previous works. The process that was used to detect the anthropometric points of the foot was incorporated into a process of creating customized insoles. By combining the technique that extracts the outline encompassing the footprint, a specific process that uses this outline to create the 2D shape of the insole and the using of 3D shape of the standard shoe-last, we have created the 3D shape of the insole adjusted to foot.
