The shoe assembly consists of a steel shoe, a cork platen, and the screws used to fasten it to your sander. The shoe assembly is the platform that the sandpaper belt rubs against on the bottom of the sander. The shoe assembly will eventually wear down, because it is in constant contact with the sandpaper belt as it rotates at high speed. The shoe assembly is considered a normal-wear item that will need to be replaced periodically. The cork can also wear down from the shoe (which can lead to uneven sanding). The steel portion of the shoe can wear thin, and eventually break off.
