TABLE-US-00001 Description of element symbols: 10 cushion pad 11 outer foot arch portion 111 middle foot portion 112 heel portion 113 air pad 12 inner foot arch portion 121 air pad 13 foot arch groove 14 connection path 20 shoe lining 30 cushion insole

[0020] In reference to FIG. 1, for the cushion pad 10 according to the first preferred embodiment of the present application, the cushion pad 10 has flexibility. The cushion pad 10 comprises an outer foot arch portion 11, an inner foot arch portion 12 and a foot arch groove 13. The outer foot arch portion 11 is formed by extending from one end of the cushion pad 10 to the other end of the cushion pad, the shape of the outer foot arch portion 11 corresponds to human foot's mid and rear parts, the outer foot arch portion 11 comprises a middle foot portion 111 and a heel portion 112; the middle foot portion 111 is disposed in on end of the outer foot arch portion 11; the heel portion 112 is disposed in the other end of the outer foot arch portion that is opposing the middle foot portion 111, and the heel portion 112 is connected to the middle foot portion 111. In this specific embodiment, the width of the middle foot portion 111 is smaller than the width of the heel portion 112. Moreover, the inner foot arch portion 12 is disposed on the cushion pad 10 and is adjacent to the middle foot portion 111 of the outer foot arch portion 11, and the inner foot arch portion 12 closely supports a human foot's inner foot arch; the foot arch groove 13 is disposed between the middle foot portion 111 of the outer foot arch portion 11 and the inner foot arch portion 12. The location of the foot arch groove 13 corresponds to the boundary between the human foot outer foot arch and inner foot arch. In the specific state of implementation, the cushion pad 10 is made from a material of thermoplastic polyurethane (TPU) elastomer.

[0021] In reference to FIG. 2 and FIG. 3, the second preferred embodiment of the cushion pad 10 of the present application is similar to the first preferred embodiment described above. In addition, the outer foot arch portion 11 and the inner foot arch portion 12 comprise the air pad 113 and air pad 121, respectively, in which the air pad 113 and the air pad 121 are respectively disposed within the outer foot arch portion 11 and the inner foot arch portion 12. More specifically, the cushion pad 10 further comprises a connection path 14, and the connection path 14 is disposed in the foot arch groove 13, the air pad 113 of the outer foot arch portion 11 communicates to the air pad 121 of the inner foot arch portion 12 by way of the connection path 14. In the specific state of implementation, the cushion pad 10 is made through a high frequency press-molding approach. In its implementation, as shown in FIG. 4, the cushion pad 10 may be placed on top of a shoe lining 20. In this way, when a person is wearing the shoes, the person's foot bottom will be provided with a desirable supporting and buffering function.

[0022] In reference to FIGS. 5 to 7, the third embodiment of the present application further comprises a cushion insole 30, which comprises the cushion pad 10 that may be disposed on the cushion insole 30 in a protruding manner, disposed on the cushion insole 30 in a recessing manner, disposed within the cushion insole 30 or disposed below the cushion insole 30.

[0023] The above descriptions are just a few preferred examples of the present application, rather than limitations to the scope of the present application in any way. Without departing from the technical scope of the present application, a person of ordinary skill in the art may make any equivalent embodiments with local change or modification based on the technical contents disclosed in the present application, which should be within the scope of the present application as well.
