ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a shoe pad assembly. More particularly, the present invention relates to a shoe pad assembly which is used as an insole.
A conventional shoe pad is made in one piece. In general, the conventional shoe pad has poor air permeable effect and poor water absorbing effect.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a shoe pad assembly which has a polyethylene terephthalate non-woven fabric layer to absorb water effectively.
Another object of the present invention is to provide a shoe pad assembly which has a gauze dipping in a solution containing activated carbon, alum, resin and ceramic powders producing far-infrared in order to form two web-shaped films on the gauze to become an air permeable layer.
Accordingly, a shoe pad assembly comprises a first layer, a second layer, a third layer, and an elastic base layer. The third layer is disposed on the elastic base layer. The second layer is disposed on the third layer. The first layer is disposed on the second layer. The first layer is an air permeable fabric. The second layer has two web-shaped films and a gauze disposed between the web-shaped films. The third layer is a water absorbing polyethylene terephthalate non-woven fabric layer.
