How roller blades are made?

Roller blades are made by first creating a lightweight, durable frame typically from aluminum or composite materials. The wheels are then manufactured using polyurethane, which provides grip and shock absorption, and are mounted on the frame along with bearings for smooth rotation. The boot, which provides support and comfort, is often made from a combination of plastic and fabric, molded to fit the foot. Finally, the components are assembled, ensuring the wheels spin freely and the boot fits securely for optimal performance.
