Question: what is the difference between roller blades and roller skates?
Answer: Rollerblades are a type of inline skates. In fact, Rollerblade is a company that made the very first “rollerblades” back in the 1980s. All inline skates and rollerblades have a single axle with 3-5 wheels on each skate. ... The larger boot and wider wheels makes skating in rollerblades easier than on inline speed skates.
