Abstract

A method for integrally weaving a shoe embryo having an extension is provided. The extension may be a vamp decoration piece, a shoe lace installation piece, an ankle strap or a toe decoration piece. During a weaving process of the shoe embryo of the method, the extension may be formed simultaneously by knitting at least one of yarns. Thus, by weaving the shoe embryo using the method of the present invention, the extension may be prevented from an additional post-process that may reduce the overall aesthetic features of the woven shoe embryo. Further, because the extension is a formed integral, a process of installing the extension after the shoe embryo is woven as in the prior art is eliminated.
