An elastic concave portion 11 that is concave inward is provided in the middle of the side surface of the midsole 1, and the upper side surface 111 and the lower side surface 112 of the elastic concave portion 11 are inclined outward in a trumpet shape. A plurality of bending protrusions 12 are provided at the front end of the lower side surface 112, and the bending protrusions 12 are arranged in sequence at the bottom of the lower side surface 112. The bending portion 121 of the bending protrusion 12 protrudes outward from the lower side surface 112, and the first free end 122 of the bending protrusion 12 is located at the front end of the bending portion 121 and is inclined toward the toe direction, and the second free end 123 of the bending protrusion 12 is located at the rear end of the bending portion 121 and is inclined toward the heel direction. In addition, the length of the second free end 123 is greater than the first free end 122.

[0036] The outsole 2 covers the bottom surface of the midsole 1 to achieve a wear-resistant effect. The midsole 1 is thick as a whole and has good elasticity. An inwardly recessed elastic recess 11 is provided on the side so that the top edge and bottom of the midsole 1 are convex. When the foot applies pressure to the midsole 1, it is convenient to compress the midsole 1 and apply greater elasticity to the foot, making the overall wearing lighter. Furthermore, a bent protrusion 12 is provided at the bottom of the side of the midsole 1, and a longer second free end 123 is provided to extend toward the heel. During the movement, the foot applies backward pressure to the midsole 1, and the extension direction of the second free end 123 is nearly perpendicular to the extension direction of the pressure. Multiple second free ends 123 are provided to provide better support for the foot, further improving the elasticity of the running shoe sole, and making it lighter during the movement.

[0037] In this embodiment, a plurality of "V"-shaped grooves 13 are arranged at the rear end of the lower side surface 112, and the "V"-shaped grooves 13 are arranged in sequence in the vertical direction. The "V"-shaped grooves 13 are located at the heel, and the "V"-shaped grooves 13 extend to the front and rear ends of the heel to support the heel, provide good support to the heel during the foot falling process, and apply greater elastic force to the heel, further improving the overall lightweight performance of the running shoe sole.

[0038] In this embodiment, an inwardly recessed elastic groove 14 is provided on the upper side surface 111, and the elastic groove 14 extends from the front end of the midsole 1 to the rear end of the midsole 1. The elastic groove 14 extends the bending section of the side of the midsole 1, further enhancing the elasticity of the upper side surface 111 of the midsole 1. Furthermore, a plurality of inclined elastic protrusions 141 are provided in the elastic groove 14, and the elastic protrusions 141 are inclined upward from the bottom thereof toward the direction of the heel. During the running process, the foot applies backward pressure to the midsole 1, and the extending direction of the elastic protrusions 141 is also close to perpendicular to the extending direction of the pressure. The plurality of elastic protrusions 141 are provided to provide better support for the foot, further improving the elasticity of the running shoe sole, and making the running shoe lighter during the running process.

[0039] In this embodiment, the outsole 2 includes a front outsole 21 and a rear outsole 22, the front outsole 21 is fixed to the front end of the bottom of the midsole 1, and the rear outsole 22 is fixed to the rear end of the bottom of the midsole 1, and the front outsole 21 and the rear outsole 22 are arranged at intervals. The front outsole 21 and the rear outsole 22 are distributed at the front and rear ends of the arch position, and the amount of the outsole 2 is reduced to save costs while ensuring that the running shoe sole has good wear resistance, and the overall weight of the running shoe sole is reduced, further improving the lightweight performance of the running shoe sole.

[0040] In this embodiment, a weight-reducing portion 211 extending inward is provided on one side of the front outsole 21 close to the rear outsole 22, and the weight-reducing portion 211 is located below the second metatarsal. The weight-reducing portion 211 further reduces the amount of outsole 2 used and reduces the overall weight of the running shoe sole. During the running process, the forces exerted on the running shoe sole by both sides of the sole are relatively large. The weight-reducing portion 211 is provided below the second metatarsal, that is, on one side of the first metatarsal connected to the big toe of the foot. Under the premise of achieving weight reduction, the tightness of the contact between the front outsole 21 and the ground is also ensured, ensuring that the running shoe sole has good anti-slip performance.

[0041] Further, a plurality of clearance grooves 23 are provided on the bottom surface of the outsole 2, which are arranged at intervals in sequence, and the clearance grooves 23 are distributed from the front end of the outsole 2 to the rear end of the outsole 2. The clearance grooves 23 reduce the overall hardness of the outsole 2. During the running process, the outsole 2 is squeezed at the edge of the clearance grooves 23, deformed toward the inside of the clearance grooves 23, and the contact time between the outsole 2 and the ground is extended, thereby improving the anti-skid performance of the running shoe sole. In this embodiment, the clearance grooves 23 extend in the width direction of the outsole 2 in a wavy shape. The clearance grooves 23 give way to the bottom surface of the outsole 2 at its edge from multiple directions to adapt to the pressure applied to the running shoe sole in different directions from the sole direction, thereby further improving the wear resistance of the running shoe sole. In this embodiment, a plurality of weight-reducing grooves 24 are provided on the bottom surface of the outsole 2, and the plurality of weight-reducing grooves 24 are distributed in sequence between adjacent clearance grooves 23, and the weight-reducing grooves 24 extend along the width direction of the outsole 2, and the length of the weight-reducing grooves 24 is less than the width of the outsole 2. The weight-reducing groove 24 further reduces the mass of the outsole 2, thereby improving the overall lightweight performance of the running shoe outsole. At the same time, the weight-reducing groove 24 further reduces the overall hardness of the outsole 2, thereby improving the anti-slip performance of the running shoe outsole. Specifically, the weight-reducing groove 24 and the clearance groove 23 are provided on the front outsole 21 and the rear outsole 22.

[0042] In this embodiment, the rear outsole 22 is a "U"-shaped outsole 2, and the opening 223 of the "U"-shaped outsole 2 faces the front outsole 21. A weight-reducing notch 221 is provided at the rear end of the "U"-shaped outsole 2. The rear outsole 22 is a horseshoe-shaped body that is fixed to the rear part of the bottom surface of the midsole 1, and is located below the heel to protect the rear end of the running shoe sole. On the premise of ensuring that the overall running shoe sole has good anti-slip and wear-resistant properties, the middle notch 222 and the weight-reducing notch 221 of the rear outsole 22 are used to reduce the amount of the rear outsole 22, reduce costs, and reduce the weight of the overall running shoe sole.

[0043] Furthermore, an elastic groove 15 and a weight-reducing slope 16 are provided on the bottom surface of the midsole 1, wherein the elastic groove 15 is located on the inner side of the "U"-shaped outsole 2, that is, the elastic groove 15 is located in the middle notch 222 of the rear outsole 22. During the running process, the heel exerts a downward force on the running shoe sole, and the pressure is transmitted downward through the midsole 1 and transmitted to the "U"-shaped outsole 2 located on both sides of the elastic groove 15 through the elastic groove 15, thereby ensuring the tightness of the "U"-shaped outsole 2 and the ground, and at the same time improving the elasticity of the running shoe sole at the heel, providing greater elasticity to the heel, and further improving the lightweight performance of the running shoe sole.

[0044] Specifically, the weight-reducing slope 16 is located between the front outsole 21 and the rear outsole 22, and is located on the inner side of the bottom surface of the midsole 1. The weight-reducing slope 16 is inclined outward from the bottom surface of the midsole 1 to the side surface of the midsole 1. The weight-reducing slope 16 is located at the arch position, where the arch position has less contact with the ground. The weight-reducing slope 16 is provided to further reduce the weight of the midsole 1, thereby improving the lightweight performance of the running shoe sole.

[0045] Please refer to the attached Figure 3 This embodiment also discloses a running shoe, comprising the above-mentioned lightweight running shoe sole and an upper 3, wherein the upper 3 is fixed on the top of the midsole 1.
