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.
One of the main reasons but not the only reason to select this ball for reviewing is the great mission of the company. If you buy one ball, they will donate one ball to the kids of developing countries against your purchase. So, this is a “Buy One, Give One” charity model, and of course, it is a good mission where you can also contribute by buying one.
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.
