[1] Scott and Brennan Olson formed the company Rollerblade, Inc., to sell skates with four polyurethane wheels arranged in a straight line on the bottom of a padded boot.
NISS, went strong for 5 years holding contests in Los Angeles, New York, Rome and Brazil.
The brand "Senate", run by Arlo Eisenberg and several other prominent skaters, enjoyed mainstream popularity during the 1990s.
Founded by company owners/skating legends Brian Shima, Jon Julio, and Kato Mateu and supported by all major skate companies, the World Rolling Series (WRS) links together the best skaters as Pablo Skorpanich, Brian Aragon, Cesar Mora, Jon Julio, event organizers, retailers and skate parks and aims to "create a tighter knit community, increase overall awareness and set a higher standard for aggressive rollerblading."
The WRS circuit started in 2009 with 10 established professional contests in France, Netherlands, England, Spain, Argentina, Australia and the United States.
Aggressive skate wheels often feature a flat profile to accommodate the impact from jumping tall heights.
In recent years aggressive skates have begun to adopt larger frames and wheels, in what is seen as a bridging of the various inline disciplines.
Aggressive skate frames are designed to accommodate the four primary wheel setups: Flat, Anti-Rocker, Freestyle and Hi-Low.
Anti-rocker wheels are typically made of high durometer urethane or plastic, allowing them to slide while grinding.
Despite not rolling on the ground, anti-rockers are capable of rotating should they make contact with hard surfaces; which many find superior to having no wheels in the center positions (a sliding hazard).
Riding without center wheels is known as a "Freestyle" setup, and offers the maximum potential space to grind.
