The juveniles of Okunoda primary school have been receiving education with bare feet life for the purpose of the growth of physical faculty.
　This study was aimed to discover the difference of the change of the foot contact area and standing ability, i. e. stability of standing posture, between bare feet and non-bare feet during six years.
　Results examined were concluded as follows ;
　1 ) The bare feet life might be more effective on the development of inside plantar arch and foot angle.
　2 ) In the bare feet life, the placement of center of gravity when standing on both feet showed the tendency of shifting forward with advance in age, and these children had a tendency of shifting more forward than the non-bare feet children.
　3 ) In the bare feet life, these children stabilized their standing posture as well as the non-bare children of 20 years ago.
　This study suggested that the standing ability of the children should be promoted with longer life of the bare feet.
