抄録

We have spent to walk the majority of the activities of daily living. We can reduce the burden on the foot by putting insoles in the shoes. In addition, insoles are used as part of rehabilitation. It can be proposed for the maintenance of a healthy life by studying the effect on the body due to the shape of the insole. This study focused on the thickness of the insoles and aimed to clarify the influence on the body when to use different insoles of the toe portion and the heel portion. Experimental subjects were opened with resting stance posture, both feet standing position and one-foot standing position. The condition of the insole was 5.5 ㎜ and 7.5 ㎜ in the thickness of the toes, and the heels were 5.0 ㎜ and 7.5 ㎜ in thickness. The experimental participants were four men in their twenties. The measuring device was a force plate. The sampling rate was 1000 Hz. From the result of the total trajectory length, it was confirmed that the center of gravity fluctuation becomes smaller by the insole.
