ABSTRACT:
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates to sports shoes and, more specifically, to a pressure-buffer insert adapted for inserting into the sole of a sports shoe to buffer the pressure of the sole of the user wearing the sports shoe.
In order to absorb shocks and reinforce the springy power of shorts shoes, sports shoe manufacturers may install air cushion means, oil bag means, and the like in the insole at locations corresponding to the ball of the foot or the heel. Because some of the material may leak when overheated, it does not meet environment protection requirements.
It is the main object of the present invention to provide a sole and pressure-buffer insert arrangement for sports shoe, which effectively buffers the pressure from the sole of the user wearing the sports shoe. It is another object of the present invention to provide a sole and pressure-buffer insert arrangement for sports shoe, which uses linked shells to hold two inflatable air bags at locations corresponding to the ball of the foot and the heel for buffering the pressure of the sole of the user wearing the sports shoe. It is still another aspect of the present invention to provide a sole and pressure-buffer insert arrangement for sports shoe, which allows the user to adjust the air pressure of the inflatable air bags conveniently.
