Lean making method for Goodyear seam shoes

The invention discloses a lean making method for Goodyear seam shoes. The method comprises the steps that all components of a shoe body are divided into standard components, namely a vamp, a welt, an insole, a packing layer and an outsole; the vamp, the welt and the insole are sewn into a whole; the packing layer and the outsole are mounted, and then a Goodyear seam shoe is made through a heat setting process and a cold setting process. According to the lean making method, five processes including upper clamping, nail pulling, upper foot cutting, grinding and upper bottom bonding in the traditional art are omitted, production cost is lowered, investment of personnel is reduced, the making process is simplified, and more consumers can put on the novel Goodyear seam shoes which are firm and durable; besides, a whole plastic piece is used as the packing layer of the insole, and the insole is more comfortable than a traditional insole filled with cork; moreover, bonding through mucilage glue is not needed, so that time and labor are saved, and environmental friendliness is achieved.
