Replacement Foot for the 13-inch, 15-inch, and 17-inch Unibody MacBook Pro. This foot is a two piece replacement foot for the original which was molded into the bottom case. They must be glued back in place. We use Super Glue. It is not the perfect solution, but carefully installed, it works and looks fine.
