To achieve good shock absorption and cushioning effects, their hardness is usually small; however, although a soft sole has good shock absorption and cushioning performance, its supporting ability for the sole of the foot becomes relatively weak correspondingly. During high-intensity exercise, such soles often cannot provide good protection for the foot. Content of the Utility Model

Detailed implementation mode

[0022] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0023] Please refer to Figures 1-5 , the utility model provides a stable-support rubber sports shoe sole, including an EVA midsole 3, a forefoot RB outsole 4 and a heel RB outsole 5. A first embedding groove 31 is opened in the middle waist part of the EVA midsole 3, a second embedding groove 32 is arranged in the forefoot part of the EVA midsole 3, and a third embedding groove 33 is arranged in the heel part of the EVA midsole 3. A first protrusion 41 clamped in the second embedding groove 32 is provided on the forefoot RB outsole 4, and a second protrusion 51 inserted into the third embedding groove 33 is provided on the heel RB outsole 5;

[0024] The rubber sports shoe sole further includes a support body 1 and a support piece 2. The support body 1 is adapted to be in the first embedding groove 31. The support piece 2 includes a first elastic sheet body 21 adapted between the first protrusion 41 and the inner wall of the second embedding groove 32, a second elastic sheet body 22 adapted between the second protrusion 51 and the inner wall of the third embedding groove 33, and a supporting sheet body 23 arranged between the first elastic sheet body 21 and the second elastic sheet body 22 for supporting the support body 1;

[0025] When the rubber middle waist is combined with the sports shoe sole, the support body 1 is arranged in the first embedding groove 31, which can form a support at the middle waist of the sports shoe sole to support the arch part of the foot, facilitating the movement and exertion of the foot. Among them, the supporting sheet body 23 of the support piece 2 is located below the support body 1 to support the support body 1, and the first elastic sheet body 21 of the support piece 2 can extend into the second embedding groove 32, while the second elastic sheet body 22 of the support piece 2 can extend into the third embedding groove 33. This design can increase the bonding area between the support piece 2 and the sports shoe, thereby improving the support performance of the support body 1, and this support piece 2 can prevent the sole from over-inverting or over-everting, enabling the sports shoe to adapt to more environments.

[0026] In this embodiment, the cross-section of the support body 1 includes an arc-shaped upper edge 12, a support side edge 13, and a clamping bottom edge 14. The included angle between the arc-shaped upper edge 12 and the support side edge 13 is an acute angle, and the arc-shaped upper edge 12 and the support side edge 13 are connected by an arc transition. The arc-shaped upper edge 12, the support side edge 13, and the clamping bottom edge 14 enclose to form a helical tooth structure. The arc surface formed by the arc-shaped upper edge 12 of the support body 1 has an arc-shaped design that can better conform to the arch part of the foot to form a better support effect. And because the overall shape is similar to a helical tooth structure, when the support body 1 is stressed, it can cause the support side edge 13 to squeeze the EVA midsole 3 and deflect towards the heel part of the EVA midsole 3. At this time, the EVA midsole 3 is squeezed and can give an elastic thrust forward to the arch part of the foot through the support body 1.

[0027] In this embodiment, the clamping bottom edge 14 is arc-shaped, and the outer arc surface of the clamping bottom edge 14 faces inwards. In the length direction of the EVA midsole 3, the supporting sheet body 23 of the supporting sheet 2 is arc-shaped, and the outer arc surface of the supporting sheet body 23 is adapted to the inner arc surface of the clamping bottom edge 14 of the support body 1. The supporting sheet body 23 is an arch-shaped structure and has a better supporting effect.

[0028] In this embodiment, a plurality of first helical tooth protrusions 211 are formed on the first elastic sheet body 21 in the length direction of the EVA midsole 3, and the inclined surface of the first helical tooth protrusion 211 faces the forefoot part of the EVA midsole 3; a plurality of second helical tooth protrusions 221 are formed on the second elastic sheet body 22 in the length direction of the midbody, and the inclined surface of the second helical tooth protrusion 221 faces the heel part of the EVA midsole 3.

[0029] After the first elastic sheet body 21 and the second elastic sheet body 22 of the supporting sheet 2 are respectively embedded into the second embedding groove 32 and the third embedding groove 33, the first helical tooth protrusion 211 of the first elastic sheet body 21 and the second helical tooth protrusion of the second elastic sheet body 22 can form a barb structure, which can improve the bonding strength between the first elastic sheet body 21, the second elastic sheet body 22 and the EVA midsole 3, and prevent the first elastic sheet body 21 and the second elastic sheet body 22 from axially sliding when the support body 1 is stressed, thereby improving the support effect of the support body 1;

[0030] Secondly, the first helical tooth protrusion 211 and the second helical tooth protrusion can respectively form "reinforcing ribs" in the width direction of the first elastic sheet body 21 and the second elastic sheet body 22, thereby improving the strength of the first elastic sheet body 21 and the second elastic sheet body 22 in the width direction of the EVA midsole 3, and thus preventing the sole from axially twisting during movement and protecting the foot.

[0031] Furthermore, several of the first helical protrusions 211 are formed by continuously bending the first elastic sheet 21, and several of the second helical protrusions 221 are formed by continuously bending the second elastic sheet 22.

[0032] Based on the above design, not only the bonding strength between the support sheet 2 and the EVA midsole 3 is increased, but also the bonding strength between the support sheet 2 and the forefoot RB outsole 4 and the heel RB outsole 5 is increased;

[0033] Secondly, on the premise that this design can avoid the axial torsion of the sole during the movement process, the sole has a certain axial bendability, so that the sole can fit the foot better during the movement process;

[0034] In addition, this design also enables the first helical protrusion 211 and the second helical protrusion 221 to have better elastic acting forces, so that the sole has a more efficient rebound performance.

[0035] Specifically, during the movement process, generally the heel touches the ground first. During this process, the inclined surface of the second helical protrusion 221 facing the heel can cause the bent part of the second helical protrusion 221 to undergo a bending deformation when touching the ground, thereby providing a more efficient rebound force. Similarly, when the sole is in full contact with the ground, the inclined surface of the first helical protrusion 211 facing the forefoot causes the bent part of the second helical protrusion 221 to undergo a bending deformation, thereby providing a more efficient rebound force. This forward feedback rebound force can provide a better boost for the foot.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
