The perfect indoor soccer ball for novice and younger players features a fabric outer layer over a thick, super soft foam layer, and an internal rubber bladder. The soft and thick foam layer helps to reduce bounces for more realistic play even off hard gym floors. In addition to the lower rebound and softer feel, this ball is about 30% lighter than most size 4 balls. All these features mean that shots and passes that hit players by accident won't hurt as much, so everyone will be encouraged to join in the game. Use indoors and outdoors on grass.
