2. Choose suitable leather, and make uppers and soles by cutting, punching and sewing.

3. Make a shoe last according to the size and shape of the upper.

4. Sew the vamp and sole with last to complete the whole shoe.

The above is the basic production process of handmade leather shoes. Different brands and styles of handmade leather shoes may be different, but the process is basically the same.
