[0030] The utility model is further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1-Figure 3 As shown, for the convenience of description, the up and down directions and left and right directions of the sole are described based on the state when the sole is normally placed on the horizontal ground. The side of the soles of the two shoes of the same pair of shoes facing each other is the inner side of the shoe, and the corresponding other side is the outer side of the shoe. The side facing the toe is the front side, and the corresponding other side is the back side. This embodiment provides a cross-country running shoe sole, including a sole body, the sole body includes an outsole 10 and a midsole 20 compounded on the outsole 10, the outsole 10 is a rubber outsole, the position of the midsole 20 corresponding to the forefoot of the human body is the forefoot part, the position of the midsole 20 corresponding to the arch of the human foot is the arch part, and the position of the midsole 20 corresponding to the heel of the human body is the heel part.

[0032] The forefoot portion is provided with receiving grooves 21 on both sides in the width direction, and each receiving groove 21 is embedded with a support piece 22 that matches the corresponding receiving groove 21. The hardness of the support piece 22 is greater than the hardness of the midsole 20. In the same receiving groove 21, the receiving groove 21 includes a first groove section 23, an intermediate groove section 24, and a second groove section 25. The first groove section 23 and the second groove section 25 are located at both ends of the intermediate groove section 24. The first groove section 23 is connected to the intermediate groove section 24, and the second groove section 25 is connected to the intermediate groove section 24. The first groove section 23 is connected to the intermediate groove section 24, and the second groove section 25 is connected to the intermediate groove section 24. The first groove section 23 and the second groove section 25 form an acute angle with the middle groove section 24 respectively. The end of the first groove section 23 away from the middle groove section 24 extends upward to the upper end surface of the forefoot portion, and the end of the second groove section 25 away from the middle groove section 24 extends upward to the upper end surface of the forefoot portion, and an eight-shaped shape is formed between the first groove section 23 and the second groove section 25. By providing a support piece 22 that matches the accommodating groove 21, the inner and outer sides of the forefoot portion are strengthened, so that the sole can provide support for the foot when facing rugged terrain, and the stability is relatively good.

[0033] The bottom of the outsole 10 is provided with a first anti-slip area 26, which is located at a position of the outsole 20 corresponding to the middle of the forefoot portion. The bottom of the outsole 10 is provided with a third anti-slip area 27, which is located at a position of the outsole 10 corresponding to the middle of the heel portion. Both the first anti-slip area 26 and the third anti-slip area 27 are provided with V-shaped anti-slip blocks 28, and the V-shaped openings of the V-shaped anti-slip blocks 28 located in the first anti-slip area 26 and the V-shaped anti-slip blocks 28 located in the third anti-slip area 27 are arranged facing each other. The V-shaped anti-slip blocks 28 on the outsole 10 are arranged linearly, so that the outsole 10 has good anti-slip performance in the linear direction.

[0034] The bottom of the outsole 10 is further provided with a second anti-slip area 29, which is arranged around the first anti-slip area 26. The second anti-slip area 29 is provided with a plurality of first block groups, each of which includes a first anti-slip block 30 and a second anti-slip block 31. In the same first block group, the second anti-slip block 31 is arranged on a side of the first anti-slip block 30 away from the rear end of the outsole 10, and a first notch 32 is provided between the first anti-slip block 30 and the second anti-slip block 31. It should be noted that the first anti-slip block 30 and the third anti-slip block 34 can be anti-slip blocks with the same structure or anti-slip blocks with different structures. In this embodiment, the first anti-slip block 30 is a quadrilateral block, and the second anti-slip block 31 is also a quadrilateral block. The outer contour diameter of the cross section of the first anti-slip block 30 and the second anti-slip block 31 gradually decreases from one end relatively close to the shoe outsole 10 to the other end, which can better hook or hang on the ground. By providing the first anti-slip block 30 and the second anti-slip block 31, the friction between the shoe outsole 10 and the ground is increased, which plays an anti-slip role. By providing a first notch 32 between the first anti-slip block 30 and the second anti-slip block 31, water on the shoe outsole 10 can be quickly drained, further improving the anti-slip effect.

[0035] The bottom of the outsole 10 is further provided with a fourth anti-slip area 33, which is arranged around the third anti-slip area 27. The fourth anti-slip area 33 is provided with a plurality of second block groups, each of which includes a third anti-slip block 34 and a fourth anti-slip block 35. In the same second block group, the fourth anti-slip block 35 is arranged on a side of the third anti-slip block 34 away from the front end of the outsole 10, and a second notch 36 is provided between the third anti-slip block 34 and the fourth anti-slip block 35. It should be noted that the second anti-slip block 31 and the fourth anti-slip block 35 can be anti-slip blocks with the same structure or anti-slip blocks with different structures. In this embodiment, the third anti-slip block 34 is a quadrilateral block, and the fourth anti-slip block 35 is also a quadrilateral block. The outer contour diameters of the cross sections of the third anti-slip block 34 and the fourth anti-slip block 35 gradually decrease from one end relatively close to the outsole 10 to the other end, so that they can better hook or hang on the ground. By providing the third anti-slip block 34 and the fourth anti-slip block 35, the friction between the outsole 10 and the ground is increased, thereby achieving an anti-slip effect. By providing a second notch 36 between the third anti-slip block 34 and the fourth anti-slip block 35, water on the outsole 10 can be quickly drained, further improving the anti-slip effect.

[0036] The outsole 10 is provided with an X-shaped through hole 37 at the position of the arch of the foot, and the bottom of the midsole 20 is provided with an X-shaped groove 38 corresponding to the X-shaped through hole 37, and the cross-sectional outer contour size of the X-shaped groove 38 gradually decreases from the opening of the X-shaped groove 38 to the bottom of the X-shaped groove 38. By providing the X-shaped through hole 37 on the outsole 10 and the X-shaped groove 38 on the midsole, not only the weight of the outsole 10 and the midsole 20 can be reduced, but also the appearance of the sole can be enriched.

[0037] The present invention has been described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments. Those skilled in the art can make various modifications to the present invention based on the existing technology, and all of these modifications fall within the scope of protection of the present invention.
