<p>PROBLEM TO BE SOLVED: To improve the bending property of a bending part, and reduce a walking load. SOLUTION: For this insole used for shoes by the Good Year Welt type manufacturing method, the flexibility of the bending part 42 of a base sheet 4 on the lower surface of which a rib 5 is provided is set to be higher than the flexibility of the toe 41 and an area 43 from the worst to the heel, which constitute the base sheet 4 together with the bending part 42. Therefore, the bending part 42 becomes easier to deform into a bow shape than conventional shoes, and the bending property is increased.</p> |
