This study aimed to determine the influence of footgear on shape of foot and physical function in preschool children who engage in this study for about 17 months. Sample size of subjects in wearing shoes and wooden clogs conditions were 12 and 10, respectively. The items of measurement in physical function of foot were digit strength, standing on one foot, foot tapping and standing broad jump.
　The foot print was measured on thirteen items ; ( 1 ) contact surface area, ( 2 ) contact area of digits, ( 3 ) contact area of sole, ( 4 ) plantar arch area, ( 5 ) foot length, ( 6 ) foot width, ( 7 ) heel angle, ( 8 ) toe angle, ( 9 ) hallux angle, (10) arch angle, (11) foot width ratio, and (12) plantar arch area ratio.
　The results were as follows ;
　After seventeen months, no significant difference was observed between shoes and wooden clogs conditions in foot length and foot width. In wearing wooden clogs condition, digit strength were significantly larger than shoes condition's one, and performance of standing on one foot and standing broad jump shows a tendency to be higher. As regards the rate of increase in contact surface area on the left foot, wooden clogs condition was significantly larger than shoes condition.
