Introduction. Recently, in the field of orthopedic support, the production of individual products based on the user’s anthropometric data has become relevant. In this regard, the introduction of digital methods into the standard technological process, which allow obtaining accurate information about the deformed foot of the patient and transforming the resulting digital model of the foot into technological equipment, guarantees sustainable demand and sales of high-quality products.
Design methods in a computer environment are powerful software tools for the development of products with a complex curved surface, which is orthopedic shoes — a construction of a complex spatial shape, consisting of mating flat parts made of various materials with different physical and mechanical properties. The introduction of modern automated design systems at individual stages of the technological process of manufacturing orthopedic shoes allows not only to find the optimal solution, but also to implement it with minimal costs.

Aim. Determine the stages of a typical technological process of complex orthopedic shoes, where it is possible to implement digital design methods.

Materials and methods. The material for the study was information obtained from 48 prosthetic and orthopedic enterprises under the jurisdiction of the Ministry of Labour of Russia, as well as an analysis of the regulatory technical base in demand in the production of orthopedic shoes. The paper uses a sociological research method, which consists in analyzing the information provided in the questionnaires concerning the equipment and software used at the stages of obtaining information about the foot, designing technological equipment and parts of complex orthopedic shoes with individual manufacturing parameters.

Results. The survey of prosthetic and orthopedic enterprises allowed us to determine the degree of use of digital technologies in the production of orthopedic shoes, including complex ones with individual manufacturing parameters.
Data from a survey of prosthetic and orthopedic enterprises in Russia showed that out of 138 units of equipment used to assess the condition of the feet and manufacture orthopedic shoes, only 8 units (5.8 %) are equipment with digital software control. The conducted research has established that domestic prosthetic and orthopedic enterprises that produce footwear products with individual parameters do not use digital technologies enough. However, this does not mean that the process of modernization of production is not available to them. The stages at which digital equipment can be used and has already been implemented are identified, for example, an automated production management accounting system, obtaining digital models of orthopedic pads, modeling and cutting of upper parts.

Conclusion. The survey of prosthetic and orthopedic enterprises allowed us to determine the degree of use of digital technologies in the production of orthopedic shoes. The stages at which digital equipment can be used and has already been implemented are identified: an automated production management accounting system, obtaining digital models of orthopedic pads, modeling and cutting of upper parts.
