, 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. They sold the company in 1984 to Bob Naegele jr., who advertised to the general public and sold millions.
The sport became popular in the United States in the 1980s and 1990s, with tens of millions of participants. Aggressive inline skating events were featured in the X Games from 1995 to 2005. Popularity waned in the 2000s, with parental concerns over injuries and the rising popularity of soccer, lacrosse, and skateboarding.

Artistic/figure skating
Artistic roller skaters use either quad or inline skates. The sport looks very similar to its counterpart on ice, but more affordable in warmer climates. Inline figure skating has been included in the world championships since 2002.
Fitness/recreational skating
Recreational skaters usually skate on roads, bike lanes, or paved trails. They might be skating solo for transportation or fitness, skating with friends, or participating in an organized event. Because urban areas tend to have more hazards from traffic, many cities have organized social groups to make skating safer.
Fitness skaters tend to skate more frequently and go longer distances. Fitness skates typically have faster bearings and larger wheels to generate speed and cover ground more efficiently. Skaters in this category tend to skate on average. Some challenge themselves to feats of endurance skating for over .
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. Currently IFSA has defined three disciplines which must be offered by any competition they sanction:

, speed slalom, and free jump. Two additional disciplines, high jump and jam, are also defined, but are at present considered optional.
Hockey
Roller in-line hockey is performed in a special rink on inline skates and was originally thought up by ice hockey players who wanted to continue training in their off season. Hockey rollerblades have wheel sizes generally in the 72–80mm 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.
Off-road skating
Roller soccer

Speed skating
Also known as inline racing, speed skating is the sport of skating (usually on flat surfaces, such as Roller rink">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 . 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. Vert skating may occur in competition and was once part of the X Games. Vert ramps are also present in many skateparks.
