Inline skates are kind of like ice skates, right?
they are a little like ice skate, but they have wheels that are lined up in a row in center of shoe.
What kind of wheels do they use?
I am not sure. I just know they have 2 to 5 wheels in a row. 
That sounds difficult to learn.
It takes practice, but they do have a rubber stop for brakes so that should help you to learn.
