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. 
Is the rubber stop in the front or back?
The brake is rubber and located on the the back of one or sometimes both skates.
