The most important difference in play is that the field is surrounded by a wall instead of touch lines. The ball can be played directly off the wall, which eliminates many frequent stoppages that would normally result for throw-ins, goal kicks and corner kicks, and generally results in a faster paced game.
Outdoor soccer cleats are not allowed on the indoor surface. Indoor soccer shoes are important for the safety and performance of a soccer player. Indoor soccer is a game that requires you to run in short bursts and be able to stop and change direction in an instant. Indoor soccer shoes contain various raised patterns on the bottom, for use on harder outdoor surfaces and on artificial turf.
