[0023] In one embodiment of the present application, the elastic sole structure provided by the present embodiment is applied to a shoe, and forms a shoe with a diagonal vamp. Please refer to Figure 1It comprises a lower sole 100 and an upper insole 200. The lower sole has a heel part 101, an arch part 102 and a forefoot part 103. The arch part 102 extends upwardly with a protruding part 110, and the top of the protruding part 110 is in an arc structure. The heel part 101 and the forefoot part 103 are provided with elastic foam pads 300, and the upper surface of the elastic foam pads 300 is not higher than the upper surface of the protruding part 110. The upper insole 200 covers the elastic foam pads 300 and the protruding part 110. After the shoe is worn on the foot of a human body, the elastic foam pads 300 of the heel part 101 and the forefoot part 102 will be pressed downward by the gravity of the human body, so that they are deformed downward, the top of the protruding part 110 protrudes, and can press and massage the arch part of the human body. Therefore, during short-distance walking, the effect of massaging the arch part of the human foot can be achieved, and the comfort of the human body can be improved.

[0024] Further, the two elastic foam pads 300 located at the heel part 101 and the forefoot part 103 are in an integrated structure. The bottom of the integrated structure is provided with a concave cavity concave upwardly, and the top of the concave cavity is provided with a clearance. The protruding part 110 extends into the concave cavity, and the top thereof protrudes from the clearance.

[0025] Further, in order to better combine the elastic foam pad 300 with the lower sole 100, the protruding part 110 can be first fixed on the lower sole 100, and the lower sole 100 with the fixed protruding part 110 is positioned in a mold. A foaming space is formed between the lower sole 100 and the cavity of the mold. Foaming material is injected into the mold, and the foaming material foams in the mold to form the elastic foam pad 300. Therefore, the elastic foam pad 300 is directly formed on the lower sole 100 by the mold, without manual bonding, which can improve the production efficiency of the sole, and the forming method can ensure the position of the lower sole 100 and the elastic foam pad 300, improve the position accuracy, and further improve the overall quality requirements of the shoe.

[0026] Further, before the lower sole 100 is positioned in the mold, an adhesive layer is coated on the upper surface of the lower sole 100, and the adhesive layer is a heat-curable adhesive material. Therefore, the foamed elastic foam pad 300 can be fixed on the lower sole 100 by the adhesive layer.

[0027] Further, in order to better connect the elastic foam pad 300 with the lower sole 100, the top of the lower sole 100 is further provided with a plurality of tapered holes, and the small end of the tapered hole faces upward. Therefore, the foaming material can enter the tapered hole to foam, and the elastic foam pad 300 can be connected to the lower insole in an inverted manner.

[0028] Further, the outer surface of the convex part 110 is also attached with a heating film 111, the inside of the convex part 110 is a hollow structure, the inside of the convex part 110 is provided with a battery 112 and a control circuit (not shown in the figure), the heating film 111 is electrically connected with the control circuit; the control circuit extends a connecting head 113 which is out of the upper insole 200, the connecting head 113 is also provided with a control switch; for controlling the heating of the heating film 111. The convex part 110 in the embodiment can also massage the arch of the human body by heating, further improving the massage effect.

[0029] Further, the convex part 110 is a hard shell structure, the upper surface of the lower insole 100 is provided with a positioning cavity, the convex part 110 is positioned and glued in the positioning cavity.

[0030] Further, referring to Figure 2 , the bottom of the lower insole 100 is relatively provided with two groups of herringbone patterns 104, the directions of the two groups of herringbone patterns 104 are relatively arranged. A plurality of horizontal groove 105 is also arranged between the two groups of herringbone patterns 104, the cross section of the horizontal groove 105 is a semicircular arc structure. So that the sole has good anti-skid effect and good softness.

[0031] The above is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
