Inline skates are boots with wheels arranged in a single line from front to back, allowing one to move in an ice skate-like fashion. Inline skates are technically a type of roller skate, but most people associate the term roller skates with quad skates, another type of roller skate with a two-by-two wheel arrangement similar to a car. Quad skates were popularized in the late 19th and early 20th centuries. Inline skates became prominent in the late 1980s with the rise of Rollerblade, Inc., and peaked in the late 1990s. The registered trademark Rollerblade has since become a generic trademark: "rollerblading" is now a verb for skating with inline skates, or "rollerblades."

Definition: The durometer rating measures a wheel's hardness. Softer Wheels (e.g., 78A): Offer more grip and absorb impacts, making them ideal for cruising and uneven surfaces. Harder Wheels (e.g., 99A and above): Provide less grip, which is perfect for performing technical tricks and slides.25 Feb 2025
