Referring to FIGS. 1 and 2, a shoe according to a conventional adhesive-type manufacturing method is manufactured by first cutting a shoe-making shoe 3 made of leather, artificial leather or synthetic material, with a sufficient margin, into a predetermined shape .

Then, an insole 5 is disposed inside, and an adhesive is applied to the inner surface of the lower end portion of the shoe-making covering 3. Thereafter, the lower end portion of the outer shell 3 is folded inward to join the insole 5 so as to surround the insole 5.

As a result, the outer shell 3 is integrated with the insole 5 to form a shoe whose lower portion is closed as shown in Fig.

Then, the shoes are finished through a process of joining the lower surface and the outer surface of the surface formed by the shell 3 and the insole 5 to the upper surface and the inner surface of the outsole 6, respectively.

On the other hand, after the manufacturing is completed, a separate insole (not shown) may be inserted on the insole 5 to improve the comfort of the user.
