The leather soles are soaked in water (through the same procedure as the welt) and wrapped in newspaper for about 24 hours, making them more manageable during the shoe making process. The next step is the re-soling, or the process of filling of the space between the tramezza and the sole with shank (a steel piece which acts as support) and pieces of cork, precisely shaped. Before being binded, the sole is glued and pressed with the hammer head which flattens out all irregolarities.
Subsequently, the next step is the re-soling, the filling of the space between the tramezza and the A (5-6 mm from the edge), which is engraved with a piece of glass, and cut creating a small channel calledCHannel (increna). On the inside, the binding of the sole with connects with the welt.
Within the sole of a shoe made with the welt process, a single line of stiching is visible which runs on the upper side of the sole and heel thus showing that the welt and the sole have not been glued together, but binded following the methods instituted by the Ars Sutoria Italiana.
