Indoor Soccer is a form of soccer played on small, indoor, artificial turf fields. Because of the smaller playing area, games are fast-paced and high scoring.

Indoor soccer is a close relative of traditional outdoor soccer, first played in the late 19th century. A smaller playing area and the ability to play the ball off of walls allows for an extremely fast style of play. Rules are similar to those of traditional soccer, except for a lack of out of bounds territory and fewer players on the field. Many leagues have instituted zone and line rule rules, similar to those in ice hockey, in order to control gameplay and create more competitive matches.

Advance a ball down an enclosed, indoor field without using hands, with the intention of putting it into the opponent's goal.

Fields are rectangular or oblong in shape, with an artificial turf surface. Walls surrounding the field are at least six-feet tall. Goals are usually smaller than traditional soccer goals. Matches are divided into four 15-minute quarters. A 15-minute overtime period is played if teams are tied at the end of regulation. Teams consist of six players, including one goalkeeper. Players may utilize the walls surrounding the field, so long as the ball doesn't go over. Rules relating to contact between players is similar to those in traditional soccer. Moves that take advantage of slick grass such as slide tackles are rarely performed due to the nature of artificial turf. Many leagues play with zone rules, which require that the ball not cross more than a certain forward distance without being touched by a player.

The first recorded indoor soccer match was played in Canada in 1885. Throughout the 20th century a number of leagues and associations, both amateur and professional, were established in Canada and the United States. Few experienced consistent growth and/or success. In 1998 the United States Indoor Soccer Association was established to promote and support the growth of indoor soccer.

Indoor soccer is a relatively safe sport due to a limited amount of intentional physical contact between players. Common injuries include strains and tears to muscles and ligaments in the ankles and knees.

Indoor soccer players should have great speed and endurance. These can be attained through both sprinting and long distance running drills.
