Fit consistency of men's running shoes

摘要

Proper fit is important for most types of footwear. Shoes are available in multiple sizes and widths to accommodate the anatomic variation of human feet. Several footwear sizing systems are being used to indicate the size and width of footwear: UK, US, EU, and mondopoint. A length increment of 4.23 mm for half sizes and a width increment of 4.76 mm for widths are used for the US sizing system (Luximon & Luximon, 2013). Shoe sizes are supposed to help retail customers buy well-fitting shoes. Ideally, all shoes labelled with the same size and width should provide the same fit. However, physical measurements (Jastifer et al., 2017; Wannop et al., 2019) and X-ray images (Jurca & Dzeroski, 2013) of shoes of the same size have shown inconsistent internal lengths and widths. Meanwhile, advancements in using foot scanning technology in retail enable the collection of foot scans and purchasing information from retail customers. These data can be utilised to determine the fit of each shoe style and size.
