Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, 2 and 3, the shoe pad for correcting patellofemoral syndrome comprises a 3D printing base layer 1, a shock-absorbing antibacterial layer 2 and a moisture-absorbing sweat-discharging layer 3, wherein the upper surface of the 3D printing base layer 1 comprises a heel area and an arch support area for supporting an arch, the heel area is provided with a heightening inclined block 12, the arch support area is provided with an arch pad 11, and the moisture-absorbing sweat-discharging layer 3, the shock-absorbing antibacterial layer 2 and the 3D printing base layer 1 are compounded, bonded and fixed from top to bottom.

The 3D printing base layer 1 is made of TPU materials through a 3D printing technology; the shock-absorbing antibacterial layer 2 is made of PORON high-performance buffer material with Microban antibacterial agent; the moisture absorption and sweat releasing layer 3 is made of cotton material; a plurality of air holes 31 are formed on the surface of the moisture absorption and sweat releasing layer 3; the heightening inclined block 12 is positioned at the left side of the heel area, and the inclined plane at the top of the heightening inclined block 12 is in smooth transition with the right side surface of the heel area and the left side surface of the forefoot.
