Inline skating

Inline skating is a multi-disciplinary sport practiced widely internationally. Inline skates typically have 2 to 5 polyurethane wheels, arranged in a single line by a metal or plastic frame on the underside of a boot. The in-line design allows for greater speed than roller skates and better manoeuvrability. Following this basic design principle, inline skates can be modified to varying degrees to accommodate niche disciplines.

Inline skating is also known as "roller blading" due to the popular brand of inline skates, Rollerblade.


Aggressive inline

In addition to speed, fitness, artistic, or skating for fun, some skaters prefer to skate aggressively. Aggressive skating is referred to by participants as rollerblading, blading, skating or rolling and refers to not only the variety of maneuvers that include a variety of grinds, airs, cess slides, toe/heel rolls and other advanced skating stunts but also the equipment used. Aggressive skates are rollerblades that include aspects of the skate that facilitates grinds, this includes a plastic frame with a space in the middle for grinding, and, soul plates that allow the practitioner to grind on the side of the boot. Types of aggressive skating include Park and Street. The range of wheel size for aggressive inline skates range from 40mm to 72mm, the median ranging in the general vicinity of 53mm - 58mm.


Park skating refers to doing tricks within a skatepark, meaning a space that is designed for skating, designed and laid out as such. Street skating specifically refers to tricks performed on non-allocated obstacles (i.e. not skate parks).

Freestyle skating

Freestyle skating is a form of inline skating performed on flat ground and refers collectively to the disciplines for which competitions are organized by the International Freestyle Skaters Association.[2] Currently the IFSA has defined three disciplines which must be offered by any competition they sanction: freestyle slalom, speed slalom, and free jump. Two additional disciplines, high jump and jam, are also defined, but are at present considered optional.


Hockey performed in a special rink on inline skates Originally thought up by ice hockey players who wanted to continue training in their off season. Hockey rollerblades have wheel sizes generally in the 70-78mm range. The toe end of the boot is characteristically squared off. The feel of the boot is generally the same as ice skates, so the switch off between hockey skates and hockey is diminished- leading to better in-training simulations of ice hockey.

Speed skating

Also known as inline racing, speed skating is the sport of skating (usually on flat surfaces, such as roller-rinks) with the intent to beat the opponent's time score or get to the finish line first.

Vert skating

A term used to refer to inline skates on a vert ramp, a half pipe with some vertical in it usually between 6in to 24in. Vert skating is a form of gymnastics performed with skates. The purpose of vert skating is to ride higher than the coping (which is the metal pipe on top of the ramp) and perform spins or flips. It focuses on complicated hard aerial maneuvers, such as spins and flips. The intent of the skater is to build speed until they are of sufficient height above the edge of the ramp to perform various aerial acrobatics. In competitions skaters have limited time, often less than a minute, to impress the judges by landing numerous and difficult tricks. The sport was included in the first X Games in 1995. Vert skating is used in a lot of competitions such as the X Games. Vert ramps are also present in most skateparks of today.


The modern style of inline skates was developed as a substitute for ice skates, for use by a Russian athlete[who?] training on solid ground for Olympic long track speed skating events[citation needed]. Life magazine published a photo of American skater Eric Heiden, training for the 1980 Olympics, using such skates on a Wisconsin road.

In 1980, a group of ice hockey players in Minneapolis, Minnesota were looking for a way to practice during the summer. 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.
