[0038] In order to further explain the technical solution of the present invention, it is described in detail below in conjunction with embodiments.

[0039] Reference Figures 1 to 7A field shoe sole comprises a sole body, wherein the sole body comprises a midsole and an outsole 10 compounded on the lower surface of the midsole. Specifically, the midsole and the outsole 10 can be adhered by using an adhesive. The present invention is described in terms of the state in which the lower surface of the sole is placed on the ground. The position of the sole body corresponding to the front of the sole is set as the forefoot portion 101, and the position of the sole body corresponding to the heel is set as the heel portion 103. The sole body forms an arch portion 102 between the forefoot portion 101 and the heel portion 103. The side of the sole body corresponding to the inner side of the instep is the inner side 104, and the side corresponding to the outer side of the instep is the outer side 105. The lower surface of the outsole 10 comprises a main body area and a raised area. The main body area has the same structure as that of a conventional sole. It can be a plane, or a corresponding curved surface can be formed at a corresponding position according to the shape of the lower surface of the sole. One of the improvements of the present invention is that: a convex area extending downward is formed on the basis of a conventional sole, and when the sole touches the ground, the convex area contacts the ground 113 earlier than the surrounding main area. It should be noted that the convex area of ​​the present application is actually a sole area with a certain area, rather than a sharp spike structure in the prior art. In the present application, the area where the lower surface of the convex area is located is much larger than the area where the lower surface of a single spike in the existing sole is located. The raised area includes a first raised area 11 and a second raised area 12 corresponding to the metatarsal bones, and a third raised area 13 and a raised fourth area corresponding to the phalanges. The first raised area 11, the second raised area 12, the third raised area 13 and the fourth raised area 14 are all provided with an anti-slip block 100 that can be embedded in a plastic or rubber track. The anti-slip block 100 can be an anti-slip area with anti-slip lines. In the embodiment, in each area, there are multiple anti-slip blocks 100. The first raised area 11 and the third raised area 13 are arranged corresponding to the inner side 104 of the sole body, and the second raised area 12 and the fourth raised area 14 are arranged corresponding to the outer side 105 of the sole body. More specifically, the first raised area 11 is arranged corresponding to the first phalange and the second phalange, and the second raised area 12 is arranged corresponding to the fourth metatarsal and the fifth metatarsal.

[0040] As a preferred embodiment of the present invention, the raised area further includes a fifth raised area 15 and a sixth raised area 16 extending downward from the lower surface of the outsole 10, the fifth raised area 15 is arranged corresponding to the inner side 104 of the heel 103, the sixth raised area 16 is arranged corresponding to the outer side 105 of the heel 103, and an anti-slip block 100 capable of being embedded in a plastic or rubber track is arranged in the fifth raised area 15 and the sixth raised area 16. After the heel 103 of the sole lands, the fifth raised area 15 and the sixth raised area 16 first contact the ground 113, achieving a gripping and stable braking effect.

[0041] As a preferred embodiment of the present invention, the raised area further includes a seventh raised area 17 extending downward from the lower surface of the outsole 10, and the seventh raised area 17 is located at the front end of the forefoot portion 101. When the forefoot portion 101 of the sole finally leaves the ground, the seventh raised area 17 stabilizes the grip and plays a role in assisting the push-off.

[0042] As a preferred embodiment of the present invention, the maximum length of the raised area extending downward relative to the main area is 10-12mm, that is, the maximum length of the lower end of the raised area protruding relative to the surrounding main area is 10-12mm, and the raised area gradually and smoothly transitions to the main area from the lower end.

[0043] As a preferred embodiment of the present invention, the first raised area 11 is elliptical, with a major axis length of 60 to 70 mm and a minor axis length of 30 to 45 mm, and the second raised area 12 is elliptical, with a major axis length of 50 to 65 mm and a minor axis length of 20 to 35 mm. The major axis of the ellipse generally extends toward the front-rear direction of the sole body.

[0044] As a preferred embodiment of the present invention, the third raised area 13 is elliptical, with a major axis length of 20 to 35 mm and a minor axis length of 20 to 30 mm, and the fourth raised area 14 is elliptical, with a major axis length of 25 to 35 mm and a minor axis length of 13 to 23 mm. The major axis of the ellipse is arranged toward the front end of the sole body.

[0045] In the embodiment, the fifth raised area 15 and the sixth raised area 16 are also substantially located in an ellipse, with the major axis of the ellipse being 82 to 85 mm and the minor axis being 76 to 80 mm.

[0046] As a preferred embodiment of the present invention, the lower surface of the midsole is provided with raised portions 200 corresponding to the first raised area 11, the second raised area 12, the third raised area 13, the fourth raised area 14, the fifth raised area 15 and the sixth raised area 16, and the upper surface of the outsole 10 forms a recessed portion (blocked in the figure and not shown) corresponding to the raised portion 200. With this structure, the thickness of the entire outsole 10 is basically the same, and a recessed portion that is recessed downward is formed on the upper surface of the outsole 10, so that a raised area is formed at a position corresponding to the lower surface of the outsole 10, and the raised portion 200 of the midsole is embedded in the recessed portion, and the raised portion 200 of the midsole is integrally formed with the midsole.

[0047] As a preferred embodiment of the present invention, the midsole includes a first midsole 21 and a second midsole 22 compounded on the lower surface of the first midsole 21, and a support plate 30 is provided between the first midsole 21 and the second midsole 22, and the hardness of the support plate 30 is greater than the hardness of the midsole. In the present invention, the Shore hardness of the first midsole 21 is in the range of 44-46C, the Shore hardness of the second midsole 22 is in the range of 47-49C, the Shore hardness of the outsole 10 is in the range of 58-62A, and the Shore hardness of the support plate 30 is in the range of 70-80D. The midsole can be made of EVA material, the outsole 10 can be made of rubber material, and the support plate 30 can be made of nylon plate, carbon fiber plate, etc.

[0048] As a preferred embodiment of the present invention, the support plate 30 extends from the heel portion 103 to the forefoot portion 101, and the support plate 30 forms a first opening 31 corresponding to the forefoot portion 101, and the first opening 31 extends from the front end of the forefoot portion 101 to the arch portion 102, and the support plate 30 forms a second opening 32 corresponding to the heel portion 103, and the second opening 32 extends from the heel portion 103 to the arch portion 102, and the support plate 30 forms a support plate portion 33 extending obliquely upward on both sides of the arch portion 102, and a reinforcing plate 34 is formed at the lower end of the support plate portion 33, and the reinforcing plate 34 is arranged at an angle to the support plate portion 33, and the support plate portion 33 is reinforced and supported by the reinforcing plate 34, so as to stabilize the arch portion 102.

[0049] As a preferred mode of the present invention, there are multiple anti-slip blocks 100, and the anti-slip blocks 100 are integrally formed on the outsole 10. In the embodiment, an anti-slip unit 1000 is provided on the lower surface of the outsole 10, and the anti-slip unit 100 is in a frustum shape. The anti-slip block 100 is integrally formed on the anti-slip unit 1000. The anti-slip block 100 has a first side wall 111, a second side wall 112, and a contact surface 113 connecting the first side wall 111 and the second side wall 112. From front to back, the thickness of the first side wall 111 gradually decreases, and the thickness of the second side wall 112 gradually decreases. The front end of the first side wall 111 is connected to the front end of the second side wall 112. The first side wall 111 and the second side wall 112 are arranged in a vertical direction and in a V-shape. The multiple anti-slip blocks 100 are divided into multiple rows along the front-to-back direction, and the anti-slip blocks 100 in two adjacent rows are staggered. The structure is adopted, the first side wall 111 and the second side wall 112 are arranged in a V shape, which can be better embedded in the plastic or rubber track. The first side wall 111 and the second side wall 112 act as a retaining wall and have a better braking effect.
