The improved approach to the development of parameters for the inner shape of military boots

In the work, anthropometric studies of the feet were performed by means of 3D scanning. The results of scanning have been used for two main purposes. Firstly, the features and morphological structure of the feet of young men aged 20-30 were studied, who are the representatives of the Ukrainian population that are subject to mobilization into the ranks of the Armed Forces. Apart from this, the quantitative distribution of the main morphological features of the feet of the sample population was analyzed. During measurements, it was noticed that a large number of men had hypertrophy of the heads of the 1st and 5th metatarsal bones. In order to rationalize the range of lasts with different sizes and fullness, while trying to fully satisfy the requirements of compliance with the anthropometric parameters of the feet of consumers, the parameters of the feet with the hypertrophy of the heads of the 1st and 5th metatarsal bones must be taken into account in the lasts with increased width. Furthermore, the results of scanning constitute the basis for calculating and developing basic parameters of lasts. For this, the work suggested the method of designing a last shape based on such types of input data as a digital foot model, dimensional foot parameters, and a foot print obtained as a result of mass 3D scanning of the feet.
