3D dynamic behaviour of foot structure may provide additional information for last design

Even though the importance of well fitting footwear has been known and studied for several years, there are still no evidence based standard guidelines available for last and shoe construction which take dynamic changes in 3D foot structure into account (Krauss et al. 2010). Instead, shoe last criteria are still based on static anthropometric measurements and on the subjective expert knowledge of last designers. Recent technical developments in the field of 3D scanning provide the opportunity to capture moving objects (Su et al. 2010). This technological advance can be used to capture dynamic foot shape during roll over process (ROP) and measure foot deformities in a fast and accurate way (Schmeltzpfenning et al. 2010).
