Steel-toe boots are a type of work shoes that have a hard piece of metal in the front of the shoe where your toes go. This metal helps protect your toes from things that might fall on them or crush them when you're working in areas with heavy objects or machines.
Imagine if you're playing with toys and accidentally drop a heavy rock on your foot. It will hurt a lot, right? But if you have steel-toe boots on, the hard metal in the front will stop the rock from hurting your toes.
Steel-toe boots are usually worn by workers who do jobs like construction, factory work, or any job where there is a risk of dropping heavy things on your feet. They come in different shapes and sizes to fit different foot sizes and can protect your toes from serious injuries.
