The purpose of this study was to analyze the walking characteristics which measured for weights, length of legs, width of hips, walking stride width of the base support, length of walking steps, angle of left and right feet, foot arch of left and right while walking The subjects were sampled form Elementary schools in Changwat Samut Prakan of 300 boys and 300 girls aged 7 - 12 years The subjects were measured of bodies and their feet were also printed for walking characteristics. The data were analyzed by Pearson Product - moment Correlation Coefficient method. The test of differential average used the data in t - test dependent. After the data were statistically treated, it was found that : 1. The relationships of weights and walking stride width of base support, length of legs and walking step length or width of hips and walking stride width of the base support in Elementary school boys and girls were at statistic level .01 2. The test of the difference in average of the angle between left foot and the right foot statistic level .01 of boys and girls in classes Parthom 1 and Parthom 2. There was no difference of boys and girls in classes Parthom 3 to parthom 6. 3. The test of the difference in average of the arch between the left foot and right foot showed no difference in the groups of boys and girls in classes Parthom 1 to Parthom 6. 4. It was found that walking characteristics of the experimental groups of boys and girls had positions of both foot tips split from each other which was different from the theory.
