The paper examines the possibility and relevance of developing and manufacturing comfortable ergonomic shoes with individual anthropometric insoles in the context of a standard footwear enterprise. The comfortableness of the shoes is achieved due to the correct anthropometrically justified shape of the last and the load-relieving anatomical insole-sole. All initial information for designing is obtained by 3D scanning of a customer's foot and its imprint on polyurethane foam on a specialized professional 3D scanner. Designing of the last is carried out in LastMaker and PowerShape software environment while designing of the insole is performed in PowerShape based on the configuration of the lower surface of the designed last, which corresponds to the relief of the plantar surface of the foot. The anatomical insole was manufactured by milling on a 3-ways CNC machine. The general process of manufacturing shoes complies with the standard technology approved at the manufacturing facility. The individuality of the shoe shape is achieved due to the individually designed shoe last and anatomical insole. Experimental wear showed that shoes produced in this way meet comfortableness requirements to a greater extent than those manufactured using standard lasts and components. The proposed shape of the insole facilitates even distribution of body weight over the entire surface of the foot sole. When walking, such an insole ensures proper functioning of all parts of the foot at each stage of a step. The goal of improving the ergonomicity and sustainability of the shoes being developed is also achieved with the help of a special upper design that combines the insole-lining and upper elements, which reduces the number of shoe components and the technological process for its manufacture.

This study was conducted to establish a set of major causal factors that influence foot pathologies and deformities for the elderly, analyzing variables such as weight and height of subjects. The study included 100 elderly female volunteers weighing between 50 and 112 kg and measuring between 148 and 184 cm in height. The sampling method used was the non-probabilistic one, based on a mixture of Henry's sampling types, using the questionnaire, and testing was conducted using measurement and observation instruments. Subjects participated in biomechanical measurements using AMTI's AccuGait System force platform, performed in Bucharest for a period of three weeks. The results show a strong correlation among the tested variables. Weight proves to be one of the most important causative factors, as there were statistically significant correlations between it and most biomechanical parameters measured. Thus, it can be concluded that as the elderly grow in weight, they undergo significant changes in biomechanical parameters, reflected in foot deformities and pathologies.
