<p>A shoe insole having superior cushioning and comfort, good resistance to buckling, and excellent retention of cushioning properties after wear. The insole consists of three layers: (a) a bottom layer having compressive strength of at least 0.3 kg/cm2 at 40% strain, (b) an intermediate layer having less compressive strength at 40% strain than the bottom layer, and (c) a top layer constructed of fabric. The three layers are laminated together and shaped to fit inside of an article of footwear.</p> |
