We all should keep in mind that the construction of a standard soccer ball is different than a street soccer ball. When you are playing on street or hard surface, you need a rough and tough ball. The shape needs to be spherical, and the cover/panels should be made out of rubber. They need to be scratch resistant as well. Not only that, if the panels are not hand-stitched with the high-quality seam there is a big chance they will not last long.
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
