Light-up shoes are shoes that have lights in them. All shoes have a specific purpose, and light-up shoes do the same thing. They have lights in them to make it easier to identify the shoe when you’re in a dark area. Some light-up shoes have a battery pack in them that you can attach to your shoe so that you don’t have to worry about running out of battery power. Other light-up shoes have lights that are located on the sides where you can easily see them.
