Much like PU or TPU for soccer ball casings, rubber is considered the best of both worlds for soccer ball bladders when it comes to striking a balance between responsiveness and air retention. Oddly enough, this balance does not actually inspire a greater adoption by either manufacturers or players, and as such, soccer balls with rubber bladders are less popular.
Considering the positives previously mentioned, you might be wondering why we think this ball is only suited for practice-even if it is one of the best training soccer balls we have seen. This is because the Nike is not that responsive-at least, not compared to match soccer balls. This is largely because this ball uses a rubber bladder. This bladder is not responsive at all. On top of that, the foam lining and TPU casing are not the most responsive either-even if the latter does have texture to help increase its responsiveness.
I purchased the Knuckle It Pro soccer ball for my sons 12 th birthday in August of 2017. When I asked what he would like for his birthday he had mentioned this ball. I had never heard of it so I began doing research on the product. We had at least 4 soccer balls at home at the time so I wasn't sure I'd go with another ball. We have one of nearly every major brand ranging in price from $15-30. He had even received a $40 ball just months before for Christmas so I really didn't see the point in one more.
The soccer ball has gone through various changes just as the football game. As opposed to yesterday’s football ball that had stitches and seams and the classic black and white design, today’s soccer balls are designed with the latest technology that lets the ball bend more, fly quicker and also dip harder. Besides, they are quite soft that they let players kick the ball further without risking injuries. https://www.youtube.com/watch?v=DGp37du0xbQ
