The term COBBLER'S CONCERN refers to the tools and materials a cobbler uses to repair shoes. An AWL is a pointed tool used to make holes in leather, which is often used to attach soles to shoes. A SOLE is the bottom part of a SHOE, usually made of rubber or leather. A SHOE is the outer covering for the foot, usually made of leather or fabric. A LAST is a form that a cobbler uses to shape the SHOE around. An insole is an inner SOLE that is inserted into the SHOE for comfort and support.
