[0033] Example

[0034] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a training shoe sole, comprising a midsole 1 and an outsole 2, with the outsole 2 being fitted and fixed to the bottom surface of the midsole 1. The outsole 2 comprises a front body 21 and a rear body 22, which are arranged in sequence along the length of the midsole 1. The front body 21 and the rear body 22 are spaced apart and form a bending groove 4 with the bottom surface of the midsole 1. The bending groove 4 corresponds to the front end of the forefoot, and the extension direction of the bending groove 4 matches the shape of the front end of the forefoot. A weight-reducing channel 221 is defined in the middle of the rear body 22, extending along the length of the midsole 1. The bottom surface of the midsole 1 is provided with an outwardly extending limiting protrusion 11, which extends into the weight-reducing channel 221.

[0035] A thicker midsole 1 is provided to improve the overall elasticity and shock absorption effect of the training shoe sole; during exercise, the front end of the training shoe sole is bent to divide the outsole 2 into a front body 21 and a rear body 22, and the bending grooves 4 are arranged at intervals so that they are located at the bending position of the training shoe sole, reducing the need to overcome the reaction force applied during the deformation of the sole itself during bending, making the training shoe sole softer during exercise; further, the rear body 22 is provided with a weight-reducing channel 221, which effectively reduces the overall weight of the training shoe sole and improves its lightweight performance, and reduces the width of the rear body 22, further reducing the need to overcome the reaction force applied during the deformation of the sole itself during bending, and improving the softness of the sole.

[0036] Please refer to Figure 2As shown, further, at least one arc groove 211 is provided on the front body 21, and the extension direction of the arc groove 211 is the same as the extension direction of the bending groove 4. In this embodiment, three arc grooves 211 are provided on the front body 21, and the three arc grooves 211 are arranged in sequence along the extension direction of the weight-reducing channel 221. In a complete walking process, the front body 21 is bent in sequence from its rear to the toe direction, and multiple arc grooves 211 are provided on the bending path to further reduce the overall hardness of the front body 21, reduce the reaction force to be overcome for bending, and improve the overall lightweight performance. Similarly, one, two or more arc grooves 211 can be provided. In this embodiment, three are provided. On the premise of ensuring that the overall hardness of the front body 21 is reduced, the fitting area between the front body 21 and the floor is also guaranteed, thereby improving the anti-slip performance of the sole.

[0037] In this embodiment, embedded channels 2111 extending along the width of the midsole 1 are provided at the bottom of the arcuate groove 211 and on both sides of the weight-reducing channel 221. The embedded channels 2111 within the arcuate groove 211 are located in the extending direction of the weight-reducing channel 221. Providing the embedded channels 2111 at the bottom of the arcuate groove 211 further enhances the flexibility of the front body 21 at the location of the arcuate groove 211.

[0038] Furthermore, the embedded channels 2111 on both sides of the weight-reducing channel 221 are connected to the weight-reducing channel 221, and the embedded channels 2111 on both sides of the weight-reducing channel 221 are tilted toward the heel, so that the rear body 22 forms a fitting portion tilted toward the toes, thereby increasing the fitting time between the rear body 22 and the ground during movement, thereby improving the anti-slip performance of the sole.

[0039] In this embodiment, front support blocks 2112 are disposed within the embedded channel 2111 at the bottom of the arc-shaped groove 211 and within the bent groove 4. Rear support blocks 2211 are disposed within the embedded channels 2111 on either side of the weight-reducing channel 221, with both ends of the rear support blocks 2211 extending into the embedded channels 2111 on either side of the weight-reducing channel 221. The front support blocks 2112 and the rear support blocks 2211 increase the hardness of the outsole 2 at the channel structure location, providing good support for the foot during walking, facilitating better force generation and enhancing training effectiveness.

[0040] In this embodiment, the bottom surfaces of both the front and rear bodies 21, 22 are formed with a plurality of arcuate grooves 212. The arcuate grooves 212 extend in opposite directions on either side of the front and rear bodies 21, 22, along the width of the midsole 1. The plurality of arcuate grooves 212 are spaced apart. During walking, the arcuate grooves 212 provide friction in all directions for the sole and increase the roughness of the outsole 2, further enhancing the anti-slip performance of the sole.

[0041] In this embodiment, the bottom surface of the rear body 22 is provided with a first partition groove 222 and a second partition groove 223. The first partition groove 222 is located between the arch of the foot and the heel, while the second partition groove 223 is located at the front end of the arch of the foot and at the rear end of the little toe. The first partition groove 222 separates the arch and heel of the rear body 22, improving the flexibility of the rear body 22 and facilitating thickening of the heel, thereby enhancing the overall shock absorption effect of the sole. The second partition groove 223 is located at the front end of the arch of the foot and at the rear end of the little toe, that is, the second partition groove 223 is located on the outside of the training shoe sole. The second partition groove 223 is located in the area of the sole with the maximum bending angle during walking. It cooperates with the bending groove 4 to enhance the flexibility of the sole in this area and further reduce the reaction force generated by the sole bending during walking.

[0042] Please refer to Figure 1 As shown, in this embodiment, the side of the midsole 1 is provided with an elastic protrusion 12 and multiple arrow-shaped grooves 13. The elastic protrusion 12 is located below the heel. The elastic protrusion 12 increases the width of the midsole 1 at the heel, thereby improving the shock absorption performance of the entire sole. Multiple arrow-shaped grooves 13 are sequentially spaced in the middle of the side of the midsole 1. The heads of the arrow-shaped grooves 13 face toward the toes, and the rear ends of the arrow-shaped grooves 13 form an upper and lower groove structure. When the forefoot moves, it exerts a downward force on the arrow-shaped grooves 13. The upper and lower groove structures increase the elasticity of the midsole 1 at this location, further improving the shock absorption performance of the entire sole.

[0043] Please refer to Figure 3 As shown, this embodiment further discloses a training shoe, comprising the above-mentioned training shoe sole and an upper 3 , wherein the upper 3 is fixed on the top surface of the midsole 1 .

[0044] In this embodiment, the upper 3 comprises a flexible gasket 31, an inner body 32, and an outer body 33 secured to the inner body 32. The inner body 32 is knitted, and the outer body 33 is provided with ventilation channels 331 extending from the front end of the upper 3 to the upper widths of the midsole 1. The inner body 32 is positioned on the inner side, fitting snugly against the foot. The ventilation channels 331 ensure excellent ventilation throughout the training shoe, facilitating air circulation between the inside and outside of the shoe.

[0045] In this embodiment, the flexible gasket 31 is located on the upper portions of both sides of the midsole 1 in the width direction and within the ventilation channel 331. The ends of the flexible gasket 31 are embedded and fixed between the inner body 32 and the outer body 33. The flexible gasket 31 is located on the side of the sole to provide a protective fit, enhancing the softness of the side of the training shoe while ensuring good ventilation.

[0046] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
