Voit's Futsal Professional Soccer Balls, guarantee all the responsiveness of a standard pitch ball without compromising durability for fast-paced play. Our futsal balls are also perfect for training and conditioning to help all soccer players master their foot skills on and off the field! Futsal (indoor) soccer balls are different from traditional soccer balls. Futsal is played with a slightly smaller ball (No. 4) with less bounce, which allows for a faster game.
