Roller skates are footwear equipped with wheels, allowing users to glide smoothly over surfaces. They typically come in two main styles: quad skates, which have four wheels arranged in a rectangular pattern, and inline skates, which have wheels aligned in a single row. Roller skates are popular for recreational activities, fitness, and competitive sports. The design of roller skates includes a boot that provides support and comfort, along with a braking system for safety. They can be used on various surfaces, including roller rinks, sidewalks, and parks. Roller skating is enjoyed by people of all ages and can be a fun way to stay active.
