The invention discloses a wear-proof shoe sole. The shoe sole comprises a shoe sole body and a rubber block, the shoe sole body comprises a toe part, a sole part and a heel part, a positioning block is integrally formed on the bottom of the heel part, the positioning block is connected with a positioning groove in the upper surface of the rubber block in a clamping mode, first threaded holes are formed in the bottom surface and the lateral side of the positioning block respectively, and counter bored holes corresponding to the first threaded holes are formed in the bottom surface and the lateral side of the rubber block respectively. According to the wear-poof shoe sole, the wear of the shoe sole body is replaced by using the rubber block which can be installed and disassembled, when severely worn out, the rubber block can be replaced so that the shoe can be normally used, and the service life of the shoe is prolonged. The positioning block on the bottom of the heel part is adopted to be matched with the positioning groove in the upper surface of the rubber block so that the rubber block can be precisely positioned; the rubber block is installed in the mode that the lateral side and the bottom are fixed at the same time, so that the rubber block is firmly connected with the heel part.
