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.
Latex bladders are used in high-quality balls. These kind of bladders are soft and provide good feeling. They offer better response and bounce than Butyl bladders, but the downside of this kind of bladder is they don’t hold the air for too long. As a result, they require filling more frequently. Air escapes due to micropores on the cover, but nowadays some balls are constructed with carbon latex bladder to help to close these micropores. As a result, the balls can hold air for a longer period.
Size 5 is the official size for professional matches. Therefore, this ball is only available in this size. Do not use this soccer ball on concreted areas. Its unique rubber uses Puma Airlock Valve Technology (PAL) in order to facilitate proper airlock technology. This ball features Perimeter Balance Technology (PBT) which enables it to maintain impressive flight characteristics.
