What is the purpose of shoe covers?  

Shoe covers serve primarily as a barrier, preventing the transfer of contaminants between the outside world and a specific environment, such as a hospital, food processing facility, or a home. They prevent the spread of dirt, dust, germs, and potentially hazardous materials tracked in by shoes, keeping sensitive areas cleaner and reducing the risk of contamination in various settings.
