Invisible heightening insole with pressure resistant function

An invisible heightening insole with a pressure resistant function is formed by an insole body layer, a heightening layer and a semi-inserted type middle bottom layer. The invisible heightening insole is characterized in that a plurality of protruded round points are arranged on the surface of the insole body layer. The heightening layer is fixedly arranged from an arch portion to a heel portion of the bottom face of the insole body layer, and the heightening layer is in an inclined shape with a low interior and a high exterior. The semi-inserted type middle bottom layer is fixed on the bottom face of the heightening layer. The insole body layer, the heightening layer and the semi-inserted type middle bottom layer finally form a three-layer structured insole body. The invisible heightening insole with the pressure resistant function is novel in structure, good in elasticity, strong in shock absorption and pressure resistant performance, good in invisible heightening effects, and comfortable to wear.
