Abstract
A method of making shoes of the type having a soft sole and an insole part used in the method. The insole part is produced by cementing a thin and soft insole sheet on a hard insole base so as to be easily peeled apart an separated. The method includes using the insole part in lieu of a conventional insole, performing a conventional lasting manufacturing method, separating the insole base from the insole sheet and leaving only the insole sheet. A highly efficient manufacturing method is thus provided by using a lasting machine.
Claims3
A method of manufacturing shoes comprising forming an insole part comprising the steps of:
- cementing a soft and thin insole sheet on a thick insole base having a rigidity and strength sufficient to withstand a lasting in such a way that the insole base may be easily peeled apart from the insole sheet, temporarily fixing the insole part on the bottom of a last with the insole sheet directed outwardly, covering the last with an upper contacting the last tightly, lasting an end portion of the upper and superposing the end portion on a peripheral end portion of the insole part, cementing the end portion of the upper and the peripheral portion of the insole part, releasing the temporary fixing of the insole part, superposing an outsole on the insole part and the end portion of the upper, cementing the outsole to the end portion of the upper, pulling out the last, and removing at least a part of the insole base from the insole part by peeling the insole base apart from the insole sheet.
