The purpose of this study is to provide basic data for the development of Lasts for leather shoes for women in their 60s by analyzing the classification and characteristics of the feet of the lasts. Methods The analysis data was a total of 52 foot-related items, including 24 three-dimensional measurement values and 28 index values for a total of 199 women aged 60 to 69 of the 6th Size Korea. The items were analyzed using the SPSS 25.0 statistic program.

The heel and the middle part were higher, and the medial Ball width was wider than those in their 20s. As a result of the factor analysis, six factors were derived: vertical foot size, horizontal foot size, outer foot shape, heel height, midfoot height, and toe angle. As a result of the cluster analysis, four factors were derived: 'I-shaped foot with high heel', 'A-shaped foot with high heel', 'H-shaped foot with low heel', and 'D-shaped foot with high midfoot and low heel'. The most common 'H-shaped foot with low heel' for women in their 60s is the representative foot shape for them.
