    摘要: A shoe insole and processing method for shoe insole are disclosed. The insole includes an insole body for the stepping of the sole of one human foot. The insole body includes an upper insole layer having a top surface and an opposing bottom surface, a lower insole layer and a bulge. The upper insole layer is cold pressed to form bulges on the upper insole layer corresponding to different areas of the structure of the human foot. Then, the lower insole layer is bonded to the bottom surface of the upper insole layer, and then, perform cold pressing forming. Each bulge has a first convex surface and a first concave surface. The top surface of the upper insole layer integrally raised to form a first convex surface. The bottom surface of the upper insole layer integrally dented corresponding to the first convex surface to form a first concave surface.
