[0001] The present application relates to the technical field of shoe soles, and in particular to a lightweight shoe sole. Background Art

[0002] Shoes are an indispensable item in people's lives. With the improvement of people's living standards, various types of shoes emerge in an endless stream, and the soles that match the shoes are also varied.

[0003] The existing Chinese patent with announcement number CN201948104U discloses an anti-slip and climbing-aiding sole, including a TPU sole body. The bottom surface of the TPU sole body is provided with two rows of TPU protrusions distributed along the length direction of the sole. Each TPU protrusion is tire-shaped, and the width direction of each TPU protrusion is parallel to the length direction of the sole.

[0004] Regarding the above-mentioned related technologies, the applicant believes that after long-term wear, the anti-slip protrusions on the bottom of some current soles are worn out, and the anti-slip performance is reduced. The soles are usually integrally molded, and after the anti-slip protrusions on the bottom are worn out, the entire sole will be discarded, resulting in a waste of resources. Therefore, there is still room for improvement. Utility Model Content
