By no means is this type of ball similar to a typical soccer ball. For starters, instead of air, its bladder is filled with foam. In this case, the ball has less bounce and is heavier in order to facilitate its purpose; meant to be used on a hard surface indoors. This size 4 ball may also have suede castings which help to stabilize the ball on a slippery floor.
It came in a large box to accommodate the ball packaging. It comes semi deflated, so it needed some pumping before throwing it out to the kids to test out for the day. They loved the feel and control. Now, I think some was in their heads from knowing it was an actual ball the tis used for the pros, the text of the outside and the material did seem to give them better control over a $30 ball
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber.
