Inline rollerblading is considered to be an extreme sport. The origin of inline roller skates goes back to the old strap-on skates of the 1930's. Somewhat improved in later years, with dual plastic wheels, and worn indoors in what were called indoor roller rinks; however, skating on wheels did not really come of age until the advent of the modern aggressive roller blades. Aggressive skates are computer designed for speed, lightness, durability, style, and visual appeal. These are a variation of inline skates; thus, inline rollerblading. Aggressive skates are worn on the streets side by side with skateboarders. Skaters (inline rollerbladers) are ofter seen by "true skaters" (skateboarders) as a nuisance tag-a-longs because the skate style is so similar, and use the same terrain and facilities (skate parks). Both do air manuevers and grind rails, curbs and similar objects. Skateboarders, rollerbladers, and BMXers do not mix well, although very often, each individual is either equally skilled in at least two extreme sports, or in all five. It is a very curious thing, that should be investigated by professionals. However, some members of the extreme sport culture, can "cross-over" and still be accpted by the youth extreme sport cult, as Shaun White. However, skateboarder Ryan Sheckler, wouldn't be caught dead with a pair of fruit boots (roller blades) on, although he would be damn good at it, and he knows that.
Man, I love skateboarding; I would like to try inline rollerblading, but I would ever put on a pair of fruit boots.
