Your helmet needs to fit your head and be worn correctly to provide the best protection. Adjust the chin strap so the helmet fits firmly but comfortably, and use the foam pads that come with the helmet to adjust the fit. The front of the helmet should sit no more than one finger-width above the eyebrows. It should not obstruct your vision, but it needs to cover most of your forehead. In addition to a helmet, always wear wrist guards.
Wrist injuries are the most common type of inline skating injury.
We also strongly recommend the use of elbow and knee pads. When skating between dusk and dawn, wear retro-reflective clothing and carry a light. Skate in control, do not overestimate your abilities. Learn the basics, especially how to stop and turn, before you skate in crowds or traffic. Empty parking lots are good places to learn.
