Abstract
A new insole for a shoes, including water in the sole called the water insole, was developed, which joined a power of walk and a period of a walk to the shock absorption of a heel and a tiptoe part in walking. A flow of water in this insole is controlled by the positions and sizes of some dams and some orifices in the insole. The foot pressures are measured for some insole and the effect of shock absorption for the new insole is verified. In addition, a massage effect to the arch of a foot part was subsidiarily provided.
