[0036] In order to further explain the technical solution of the present invention, it is described in detail below with reference to the accompanying drawings.

[0037] Reference Figures 1 to 6 A shock-absorbing sole with stable support function includes a sole body 100, which includes an outsole 20 and a midsole 10 composited on the outsole 20. The side of the sole body 100 corresponding to the outside of the instep is called the lateral side 105, and the side corresponding to the inside of the instep is called the medial side 104. The position of the sole body 100 corresponding to the front of the sole is called the forefoot portion 101, and the position of the sole body 100 corresponding to the heel is called the heel portion 103. The position of the sole body 100 corresponding to the forefoot portion 101 and the heel portion 103 is called the mid-waist portion 102. The present invention also includes an elastic block 40 and a support block 30 disposed between the midsole 10 and the outsole 20. The elastic block 40 is disposed at the lateral side 105 of the heel portion 103, and the support block 30 is disposed at the medial side 104 of the heel portion 103. The hardness of the elastic block 40 is less than that of the support block 30.

[0038] As a preferred embodiment of the present invention, the hardness value of the elastic block 40 is 40 to 45 on the AskerC hardness scale, the hardness value of the support block 30 is 55-60 on the AskerC hardness scale, and the hardness value of the midsole 10 is 50 to 55 on the AskerC hardness scale.

[0039] As a preferred embodiment of the present invention, the elastic block 40 extends from the front end of the heel portion 103 to the rear end of the heel portion 103 and extends around the heel portion 103 to the rear end of the inner side 104 of the heel portion 103, and the support block 30 extends from the front end of the heel portion 103 to the rear end of the heel portion 103. The elastic block 40 and the support block 30 together form a U-shaped block, and the heel portion 103 of the midsole 10 is embedded in the U-shaped block.

[0040] As a preferred embodiment of the present invention, the lower surface of the midsole 10 is provided with a mounting groove 13 extending upward from the circumference of the lower surface of the midsole 10. A U-shaped block is positioned within the mounting groove 13, allowing the sides of the midsole 10 to smoothly mate with the sides of the U-shaped block. An annular retaining protrusion 14 is integrally formed within the mounting groove 13, and a perforation is formed within the annular retaining flange. The annular retaining protrusion 14 and the mounting groove 13 together define a space for positioning the U-shaped block, facilitating its installation and fixation. Furthermore, the perforation within the annular retaining protrusion 14 reduces the weight of the sole body 100, increasing the deformation space at the heel of the sole body 100 and enhancing the shock absorption effect.

[0041] As a preferred embodiment of the present invention, a first cavity 11 is provided in the heel portion 103 of the upper surface of the midsole 10, and the above-mentioned perforation is connected to the first cavity 11. The first cavity 11 extends downward from the upper surface of the midsole 10, and the first cavity 11 extends from the rear end of the heel portion 103 of the midsole 10 to the front end of the heel portion 103 of the midsole 10. The first cavity 11 is filled with a first shock-absorbing block 61, and the hardness value of the first shock-absorbing block 61 is 40 to 45 on the Asker C hardness scale.

[0042] As a preferred embodiment of the present invention, a second cavity 12 is provided in the forefoot portion 101 of the upper surface of the midsole 10. The second cavity 12 extends downward from the upper surface of the midsole 10 and extends from the front end of the forefoot portion 101 of the midsole 10 to the rear end of the forefoot portion 101 of the midsole 10. The second cavity 12 is filled with a second shock-absorbing block 62, and the hardness of the second shock-absorbing block 62 is 40 to 45 on the Asker C hardness scale. In the present invention, different hardnesses or different materials can be used to meet the different support requirements of various feet. In this embodiment, the first shock-absorbing block 61 and the second shock-absorbing block 62 are made of popcorn material commonly used in the footwear industry.

[0043] As a preferred embodiment of the present invention, the midsole 10 forms a support portion 17 between the first cavity 11 and the second cavity 12. The width of the support portion 17 near the inner side 104 of the sole body 100 (i.e., the length of the support portion 17 in the front-to-back direction) is greater than the width near the outer side 105 of the sole body 100. With this structure, the support portion 17 is designed to be smaller on the outer side 105 and larger on the inner side 104, thereby providing better support performance on the inner side 104 of the waist portion 102 of the outsole 20. Preferably, an extension portion 18 is formed near the outer side 105 of the forefoot portion 101 of the midsole 10, which is recessed toward the second cavity 12. This extension portion 18 allows for more direct force transmission before the sole body 100 leaves the ground, reducing energy loss.

[0044] As a preferred embodiment of the present invention, an anti-twist block 50 is provided on the lower surface of the middle waist portion 102 of the midsole 10. The anti-twist block 50 is disposed between the midsole 10 and the outsole 20. In an embodiment, a portion of the anti-twist block 50 is sandwiched between the outsole 20 and the support block 30, and a portion of the anti-twist block 50 is sandwiched between the outsole 20 and the elastic block 40. The hardness of the anti-twist block 50 is greater than the hardness of the midsole 10. Preferably, the hardness of the anti-twist block 50 is greater than the hardness of the midsole 10 and the support block 30. In an embodiment, the hardness of the anti-twist block 50 is 90 on the Asker C hardness scale.

[0045] As a preferred embodiment of the present invention, it further includes a first reinforcement block 51 and a second reinforcement block 52 integrally formed on both sides of the anti-twist block 50. The first reinforcement block 51 and the second reinforcement block 52 are made of the same material as the anti-twist block 50. The first reinforcement block 51 extends upward and is compounded on the inner side 104 of the midsole 10, and the second reinforcement block 52 extends upward and is compounded on the outer side 105 of the midsole 10. The cross-sectional area of the first reinforcement block 51 along the height direction is greater than the cross-sectional area of the second reinforcement block 52 along the height direction. Specifically, the span of the first reinforcement block 51 along the height direction and the length direction are both greater than the span of the second reinforcement block 52 along the height direction and the length direction. In an embodiment, the cross-section of the first reinforcement block 51 and the second reinforcement block 52 along the height direction is generally triangular, and the two are different in size. The first reinforcement block 51 and the second reinforcement block 52 form a three-dimensional wrapping support for the middle waist portion 102 of the midsole 10.

[0046] As a preferred embodiment of the present invention, the present invention further includes a hollow groove 15 provided on the forefoot portion 101 of the sole body 100, the hollow groove 15 extending from the lower surface of the outsole 20 to the lower surface of the second shock-absorbing block 62, and the hollow groove 15 extending along the front-back direction of the sole body 100. In the embodiment, the hollow groove 15 is arc-shaped. Figure 3 In the figure, two hollow grooves 15 are shown. A plurality of strip grooves 16 are also provided in the forefoot portion 101 of the sole body 100. The strip grooves 16 extend from the lower surface of the outsole 20 into the midsole 10. The plurality of strip grooves 16 are arranged in the front-to-back direction of the forefoot portion 101, and each strip groove 16 extends in the medial and lateral directions of the forefoot portion 101. The design of the hollow grooves 15 and strip grooves 16 can reduce the weight of the sole body 100 while increasing its flexibility and bendability. When the sole body 100 touches the ground, the transition from the lateral side 105 to the medial side 104 is smoother and more natural.

[0047] Furthermore, the periphery of the upper surface of the midsole 10 forms an upwardly extending side wall, and the side wall located on the inner side 104 and the side wall located on the outer side 105 are asymmetrically designed. The side wall on the inner side 104 of the mid-waist portion 102 is higher than the side wall on the outer side 105, further improving the support performance of the inner side 104 of the mid-waist portion 102.

[0048] The product form of the present invention is not limited to the illustrations and embodiments of this case. Any appropriate changes or modifications made by anyone with similar ideas should be deemed to be within the patent scope of the present invention.
