The following is based on some research I have done about this occupation:
The calzolaio or cobbler was unlike his counterpart here in the United States. He did not repair old shoes, as did those who were called ciabattini. The shoe repairman worked in a shop near to where the cobbler’s shop was located in the town. The cobbler, instead of repairing old shoes, custom-made new ones for those who were financially well-off and/or of distinction. He was almost always consigned his work on Sundays, or on town market days. The contadini, or peasants, were never his customers though. These poor people typically wore sandals, which they purchased from traveling merchants at local markets. The cobbler would never condescend to make the type of shoes they needed.
A cobbler always owned a town shop which normally had walls filled with hides or skins of all different kinds, which would be used in the making of shoes and their soles. He also had wood forms to shape the shoes, and a variety of tools, such a hammer, which would be used to nail the sole to the bottom of the shoe, pincers, which were like forceps, and needles to use for whatever sewing had to be done. He would also have polish that a beekeeper had brought to him to use on his finished product
