The invention discloses knitted shoe bodies, a producing method and knitted shoes. The knitted shoes are knitted shoe bodies which are integrally shaped by knitting, the knitted shoe bodies comprise shoe body heel portions, shoe body head portions, shoe body upper portions and shoe body sole portions, wherein the knitting yarns of at least one of the shoe body heel portions, shoe body head portions and shoe body sole portions of the knitted shoe bodies comprise thermal melting filaments. According to the knitted shoe bodies, the knitted shoes are integrally knitted by adopting knitting yarns,the knitting yarns are soft and elastic, so that the comfort degree of the knitted shoes is high, the thermal melting filaments are added to at least one parts of the shoe body heel portions, shoe body head portions and shoe body sole portions of the knitted shoe bodies, and therefore the comfort degree of the knitted shoes is maintained while the appearance of the shoe bodies is upright. The knitted shoe bodies are knitted shoes which are integrally shaped by knitting, compared with the process in which upper sheets are knitted and then cutting and stitching processes are conducted, the producing process of the integrally shaped knitted shoe bodies is simple, the efficiency is high, and easy unsewn of stitching positions is prevented.
