A cavity matched with the shoe outsole in shape is formed in the middle of the shoe outsole. An annular sewing groove for a vamp to be sewn and an annular insertion groove for the shoe insole to be fixed are formed in the opposite positions of the outer side wall and the inner side wall of the shoe outsole respectively. A uniform sewing support with the moderate thickness is formed between the annular sewing groove and the annular insertion groove. The glue-free shoe sole has the advantages that the shoe outsole and the vamp are fixed without glue, the shoe outsole and the insole are fixed without glue, sewing is convenient, and the shoe insole is well fixed and can be freely disassembled and assembled. |
