Shoe plates, also called shoe rails or landing tread, are the horizontal piece that sits on the floor into which the balusters and posts are attached. They are often the linear continuation of the false tread caps running up the sides of a staircase. Shoe plates and shoe mouldings provide another dimension and the bottom boundary of the balustrade with their accompanying mouldings treads and optional aprons. They come in a variety of sizes and profiles to accommodate numerous situations. They can be as simple as basically a finished board to a detailed profile plowed for balusters and fillet. The width is an important consideration as to whether the shoe plate will butt into the newel post or if it is wider than the post base which can sit on top of it.
