Abstract
In order to design infant's shoes easy to walk, morphological data measured in upright standing state and footprints collected in walking were studied for 49 infants of 1 to 6 years old. The measurement of the foot part and that of the hand part show that the growth curves are strikingly similar to each other for each build structure. The footstep and the stride increase with the age, and the increase is great in the period of from 2 years old to 4 years old . The walking angle tends to turn outward according to the formation of the plantar arch, and the formation of the plantar arch is httle for an examinee free from the outward turning tendency of the walking angle. The grounding area of the sole of the foot is large for the right foot in upright standing posture and large for the left foot in walking state. The path of the gravity center of infant in walking does not correctly pass through the metatarsal fibula revealing the incomplete state of the center walking.
