Hi, do you know anything about inline skates? 
Nope! I here to learn.From what I know ,skates are supposed to be flat boards slides on a slope ,I hope I'm right ? Lol!
Haha, well, there are many different kinds of skates. The ones I used when I was a kid were inline skates called rollerblades. I rode around on them all the time.
Roller blades are what ? Is it a type of skate?
Roller blades are a type of inline skate that you use to "roll" or "skate" along the road or sidewalk. They are used in roller hockey or for fun at a skating rink.
Interesting ! Do you know the earliest history of skates ,especially the ice skating?
No, I do not know the earliest history of ice skating. I did hear that ice skates may have been used by vikings almost 10,000 years ago. They were made of animal bones and leather.
