These are the first shoes that the owner's mother wore. They are traditional Lancashire weavers' clogs. They are iron-clad, as opposed to wooden-clad. The weavers couldn't wear wooden-clad clogs because they would get damp - they had to keep the floor wet for the cotton. Lancashire clog-dancing was a result of everyone wearing these shoes. The dancing is a result of the noise of the clogs moving in rhythm to the machines - and also because the work was boring.
