Abstract
An inner sole structure for a sports shoe includes an upper sheet, a lower sheet below the upper sheet, and a wavy corrugated sheet interposed between the upper and lower sheets. The wavy corrugated sheet has at least two downwardly convex protrusions that form voids between the wavy corrugated sheet and the lower sheet, and that are in sliding contact with an upper surface of the lower sheet. The downwardly convex protrusions of the wavy corrugated sheet slide longitudinally along the lower sheet member when they are subjected to compressive deformation.
