Fifty-five subjects of male and female children ranging from three to four and half years old have been measured. These subjects had already been measured in 1984 and reported in Part 1. The growth of feet during two-year period have been discussed and reported as follows:
(1) The mean values of growth of 2 years' period for the foot, stature and weight are constant and no significant difference has been found between males and females or among any age-groups of three to six.
(2) The average rates of growth of 2 years' period in age en bloc were 10.1% in males and 11.5% in females for ball joint girth, 9.9% in males and 9.8% in females for instep girth, 14.0% in males and 16.1% in females for instep height, 9.1% in males and 9.8% in females for foot length, 8.4% in males and 7.8% in females for foot breadth, 7.1% in males and 8.5% in females for minimum leg girth.
(3) In the ratios of each measurement of the foot to stature, the ratio of instep height to stature is constant but the others decrease gradually with age in both sexes.
(4) In the ratios of each measurement of the foot to foot length, the ratio of instep height to foot length increases with age but the others are constant.
(5) The ratios of each measurement of the foot to weight decrease distinctly, which means that increase of weight is rapid compared with foot growth.
