What is the definition of a roller skater?

A roller skater is defined as a person who wears footwear equipped with wheels attached to the bottom. This footwear is specifically designed for skating on various surfaces, which distinguishes it from regular shoes or other types of activities such as skateboarding or rollerblading. The unique design of roller skates allows for movement and maneuvers that are characteristic of skating, making this definition accurate and precise. In this context, someone wearing ordinary shoes or engaging in skating activities with inline skates or skateboards does not qualify as a roller skater. The emphasis here is on the footwear itself and its specific purpose for skating.
