Inline skates are a type of roller skate where the wheels are arranged in a single line, rather than in pairs like traditional roller skates. This design allows for greater speed and maneuverability, making them popular for recreational skating, fitness, and sports like hockey and speed skating. Inline skates typically have a boot that provides ankle support and a braking system for stopping. The wheels of inline skates are usually made of durable rubber and come in various sizes, affecting speed and stability. Skaters can choose from different types of inline skates, including recreational skates, fitness skates, and aggressive skates, each designed for specific activities and skill levels.
