Evaluation of protective footwear fit for older workers (60+): A case study using 3D scanning technique

Abstract Recent development of commercially available scanning systems allowing to easily obtain 3D digital representations of human body parts offers new possibilities in reliable footwear fitting evaluation, especially in older persons were foot deformations are very widespread. The present study examines degree of footwear fit of two footwear models designed for workplace conditions in younger and older users using handheld flash bulb 3D scanner. 3D scans were used to precisely measure the feet in a way that corresponded with the internal dimensions of footwear specified in the appropriate standard on shoe last dimensions. The degree of fit was compared between the two groups of workers by means of a specially developed footwear fit coefficient. Preliminary results confirm the usefulness of the developed method in evaluation of footwear fitting, in particular in identifying footwear's segments that could hinder its ergonomic properties. This indicate an interesting research avenue requiring further investigative efforts.
