Okay, so sometimes when people build houses or buildings, they like to put a secret inside. One of these secrets is called a "concealed shoe." A concealed shoe is when someone hides a shoe inside the walls or floors of their building.
Now, you might be wondering, "why would someone want to hide a shoe in their building?" Well, it's a tradition that started a long time ago. People used to believe that if you put a shoe in your building, it would bring good luck and protection. They thought that by hiding a shoe inside the walls, it would keep the building safe from bad luck and evil spirits.
Sometimes, people would use their own shoes, but other times they would use someone else's shoes. Even famous people like George Washington and Benjamin Franklin put shoes in their buildings!
Today, people still find concealed shoes in old buildings. It's like a little piece of history that's been hidden away for a long time. So if you ever find an old shoe inside the walls of a building, you know that it was put there a long time ago for good luck and protection.
