Are rollerblades like in-line skates? - Answers

The term "rollerblades" is actually used interchangeably with inline skates. The largest inline skate dealer in the world is the Rollerblade company and their name has become the common place phrase for inline skates. Think in terms of the phrase kleenex. There is actually a company called Kleenex, and there are other companies that make tissue paper as well. However, most people just say kleenex in place of tissue. The same is done with Coke. So to ultimately answer your question, rollerblades are like inline skates because rollerblades are inline skates.
