Okay, so I assume you want to skate on quads.

I would recommend to just get some cheaper, maybe used skates, I would recommend softer wheels.

Also, get protective gear and wear it:

• helmet
• elbow pads
• kneepads
• wrist protectors
• maybe even a pair of crash pants

The protection can help take away fear of falling, which is so important for making progress.

Start on flat surfaces, learn how to brake as soon as you are able to gain some momentum. There are many good tutorials on youtube (Indy Jamma Jones, Skatie, Dirty School of Skate, …).

If there is a quad skating community in your area try getting in contact, it is much more fun that way. Maybe there are rinks where you live, offering beginner courses. And don’t be afraid of falling, everybody had to start somewhere.

Focus on the basics first, then progress to park and jam stuff. Good luck and have fun!
