Anthropometric Dimensions of Foot in Northwestern Iran and Comparison with Other Populations

Foot anthropometry will enhance the fit and comfort of shoes. There are limited published data on the foot anthropometry of Iranians. Therefore, this study aimed to collect foot anthropometric data in northwest Iran to compare dimensions between the two genders and also with the corresponding data from other populations. A total of 21 dimensions of the right foot were measured in 290 males and 290 females using a digital caliper and a tape. Digital patterning and different percentile values were calculated. Independent t-test was applied to test the effect of gender on foot dimensions. Cohen’s d was computed to express the magnitude of dimensional differences between the participants of the current study and others. The absolute foot dimensions of males were significantly larger than those of females. After normalization to the foot length, however, some foot dimensions of females were found to be larger. The relative proportion of digital patterning of I and II were 78% and 22% respectively. Digital patterning and the main dimensions such as foot length and width were different among the participants of the current study and those of other populations, especially the East Asian communities. The data of this study could be utilized by local footwear designers. In accordance with the relative foot dimensions, the female foot was not a scale-down of the male foot. Therefore, women’s data should be used in designing their footwear. Compared with other populations, the participants of this study had individual foot morphology, which should be considered in the design and import of footwear.
