Improvement of the Method of Calculating the Shoe Size by Incomplete Display of the Footprint Formed by the Sole

Abstract

Anatomical and functional features identified by footwear traces are considered. The calculations specified in the methods of the trasological examination were checked for the dimensional characteristics of shoe soles manufactured by modern manufacturers. The calculation for determining the size of shoes was made according to the trace, which was displayed fragmentally. As a result of the measurements, it was found that when calculating the incomplete display of the footwear sole trace, namely its heel part, a large error was revealed in determining the real size, the width of which depends on both the type of footwear, model, its shape, and the manufacturer's shape blank part. The soles of shoes of different types, models and styles were measured, as a result of which it was proved that in addition to the method of calculating the trasological examination available in the production methods, in order to establish the size of the sole of the shoes by fragmentary display of the trace of the sole of the shoes, namely when displaying the heel or sweeping part, the most stable result is possible when displaying the intermediate part of the sole of the shoes. The average coefficient of dependence of the intermediate part of the shoe sole on the length of shoes of different types is calculated, the shape, as well as the preparation of the manufacturer's form, after which the author's improved procedure for establishing anatomical and functional features is proposed, in particular the conduct of preliminary diagnostic studies in order to determine the size of the footwear on the incomplete display of the trace, formed by intermediate part of sole of boots, army boots, half-boots, sports shoes with solid sole and shoes with minimum error depending on completeness of studied shoes.
