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.
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. https://www.youtube.com/watch?v=j2Xn84L3Kcs
