Abstract. Results of the study of the interaction of the foot with the support surface during walking in the phases of support and rolling are presented. The research is based on experimental data on flexion–extension–pronation and supination of the ankle joint and foot reactions when walking. The main attention is paid to the analysis of the transverse component of the reaction forces. It was found that it is advisable to model the shock components of the foot reaction forces using generalized Hermite functions, and the phase of the foot roll with a twisted elastic reinforced cylinder. The results of the study are used in the development of mechatronic ankle orthoses. They are aimed at developing methods for assessing and identifying flat feet in the early stages of development with the prospect of building rehabilitation maps
