What is the average foot size of a five-year-old boy?
Is that the African or European five-year-old boy? Also, is the
five-year-old boy laden or unladen? The average foot size of a
laden five-year-old boy can increase from one-half to one full
size, depending on the time of day of the measurement. Measuring
later in the day will result in a larger average foot size for both
laden and unladen five-year-old boys. However the difference will
always be lesser for unladen five-year-old boys.
