Today’s generation of the ball allows teams to be more accurate with their passing and their shots, leading to a myriad of strategies being employed.  Some simply wait and try to shoot from way outside because of the wall the ball flies.  Others use the ball on the ground.  Whichever way, we are certainly all lucky to be able to use today’s technology in our games!  There are a few things to consider when buying a soccer ball.  There are various sizes, materials, qualities, and levels of play which will help determine which one you need for your specific purposes.
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.
The most commonly used materials for casing are PolyUrethane(PU) and PolyVinyl Carbonate (PVC), synthetic leather or a combination of PU and PVC. You can distinguish the type of casing used by touch. Balls that uses PVC usually have a hard exterior but are cheap and durable. PU cased balls are softer to the touch, high in quality and more responsive than PVC balls. Synthetic leather balls offer increased control hence ideal for professional matches or high-level playing. You will also notice a glossy finish on all soccer balls. This comes in handy in minimizing scuffing and water damage to the balls.
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. https://www.youtube.com/watch?v=c1SVcjYY6TE
