In order to design the functional shoes proper to low-aged infants, morphological measurements on eighty nine infants from 12 to 51 month old were made.
　Results were as follow:
　1) In infants from 24 to 51 month old, growth of length and girth is more rapid than that of width.
　2) Measurement for feet of infants is not become larger as their age. Morphological measurements for feet of infants before 2 years old clearly differ from that of after 2 years old.
　3) Weight is highly correlated with their feet shape. Therefore weight is characteristic item to understand the feet of low-aged infants.
　4) In cross section at the ball girth and at the instep girth, the peak point of cross section tends to move towards the inside (from 1:1 TO 3:2 fig. 11,12) with age.
　Dorsal contor at the ball girth tends to be flat and the height at the instep girth tends to be larger with age and weight. It is found that infants under 4 years old have great change in growth of their shape of instep.
