Proper shoe sizes for Thai elderly.

BACKGROUND Problems from improper shoe fitting are common, but there are limited foot data for the older Thai population. OBJECTIVES To study foot dimensions and determine proper shoe sizes for Thai elderly. METHODS Healthy older people: 108 men, 105 women, aged 60-80 years, who were independent in walking, were recruited. Thirteen foot dimensions and current shoes used were measured. Side-to-side, gender difference, and correlations of main foot measurements were analyzed. RESULTS About 50% women and 34% men wore too narrow shoes, and this was found to be associated with foot pain. At the same foot length (FL), men had larger foot width (FW) and toe depth. Foot width=2.39+(0.29 x FL), r=0.50, p=0.001 for women and=2.48+(0.31 x FL), r=0.56, p=0.002 for men. Arch length=1.0+(0.7 x FL), r=0.93, p=0.001 for both genders. Toe depth had constant values in all shoe sizes of each gender. Correlations of other foot parameters were reported. CONCLUSIONS These anthropometric data is essential for proper shoe fitting in order to provide foot ergonomics and prevent foot problems for older Thai people.
