In-line skates are roller skates that most commonly come with four wheels all in a row attached to each boot. To many people in-line skating is nothing more than a recreational activity. Then, there are those that take the sport to a higher level. Author Jeff Savage takes a look a ten of the most exciting and creative in-line skaters ever: from the sport's pioneers, such as Chris Edwards and Kate Gengo, to today's young stars such as Randy Spizer, and Fabiola da Silva. Other skaters featured include Manuel Billiris, Arlo Eisenberg, Dawn Everett, Tasha Hodgson, Matt Mantz, and Eric Schrijn.
