The purpose of this study was to identify the sizing problems for shoes, and provide improvement information for shoe industries in internet shopping mall. For this, the study was conducted through a survey with 611 young women consumers from late 10s to late 20s. In addition, we investigated the actual conditions of shoe size system from manufacturers and vendors of internet shopping mall. On the survey from consumers, it was revealed that the main reason which makes the consumers hesitate to purchase is the difference between the image or size shown by the monitor and the actual product. Also, the problem was substantiated through status of internet shoe vendors. Moreover, it was found that consumers rarely have the knowledge of the letter sizes for the foot girth at purchasing shoe. To overcome the problems of shoe size system in internet shopping industry, the new sizing system that both consumers and vendors can satisfy is needed immediately.

This is a tentative study to provide prototype of sizing system for children's shoes. For this study, 364 elementary school girls from KyungIn and YeongNam areas were participated in the measurement. The results of the analysis on four measurement items related to foot can be summarized as followings: 1. All of the foot related items were increased according to their growth. Especially, foot length, foot width, and toe width showed a high correlation. 2. The result also revealed that the current sizing system can cover only 70.9% of children in measurement, which means that a new sizing system is required. 3. We suggested a new standard size for foot size/foot circumference based on the results above according to current sizing system, and a new standard size for foot circumference/foot width based on ISO standard. The results of this study would be helpful in the design of sizing system of children's shoe if applied with the raw data of the Size Korea recently measured.

This study aims to categorize age groups for shoes manufacturing including shoes size and boot tree development for Koreans. In order to carry out the research, the characteristics of different parts of foot in relation to size are analyzed according to age and sex, making use of human body measurement database. As a result of statistical analysis, it was found that the measurement items such as foot length, metatarsal tibiale, foot breadth and instep circumference of a person reached the range of standard deviation and average numerical figures of an adult group (18-24) from the age of 14 in men's case, and from 12 for women's case, which indicates the time of completion of their foot growth. Based on these findings where males of 14 years old and females of 12 are within similar measurement range to adults, it is necessary to categorize the age groups for shoe sizing system into the following four groups: males 13 years old or under, males 14 years old or over, females 11 years or under, and females 12 years or over. The proportional measurement produced by dividing each measurement item of foot parts by foot length was compared in an independent samples t-test, and there were meaningful differences according to different foot shapes of the two age groups of males 13 or under - males 14 or over, and females 11 or under - females 12 or over. Also, the independent samples t-test for the age groups of males 13 or under - females 11 or under, and males 14 or over - female 12 or over, showed similar meaningful differences, which indicates the differences in foot shapes of male and female during the period of growth.

The purpose of this study were to analyze the anthropometric data of feet of Korean women with aging, to categorize the women's foot shapes, and to compare the shoe size according to the foot shapes in order to provide the basic information for more comfortable shoes. Subjects of this study were 181 women over age 20. They were measured with the direct measurement method and the indirect measurement method. 26 items were measured from the right foot and 6 items were taken on foot outline. Factor analysis, cluster analysis, analysis of variance, post-hoc test, and cross tabs were peformed for statistical analysis of the data by SPSS program. There were significant differences in height items, breadth items, girth items, and angle items by subjects' age. The older subjects' feet were wide and thick with big deformity on toes. The arch height of the older ones was low. This implicates that the degree of deformity on toes, the foot ratio, the foot girth, the foot breath and the arch height as well as the foot length are needed to be considered in developing comfortable shoes. Nine foot construction factors were extracted by the factor analysis of anthropometric measurements; foot size factor, heel and instep factor, malleolus lateralis factor, malleolus medialis factor, foot shape factor, shape of toes factor, heel height factor, big toe height factor, and internal factor. On the basis of the cluster analysis, three different foot shapes were categorized. Type 1 was large and wide foot with little deformity on little toe. Type 2 was medium foot with deformation of big toe, and with the lowest arch height. Type 3 was small and narrow foot with the highest arch height. Distribution of shoe size according to the foot shape was analyzed. The ball of foot breath was of wide distribution than the ball of foot girth. This implicates that girth items and breath items of the foot should be enclosed for the same foot length in the shoe sizing system.
