Just received the ball and was pleasantly surprised. I took it outside with my high school aged kids and kicked it around. We only played for about 15 minutes, but I couldn't find anything to gripe about. It's a slightly textured ball and flew true. I'm probably going to order several for my high school soccer team and see if they hold up over time. I did NOT like that it shipped inflated though.
When it comes to soccer ball bladders, you will generally opt for the material that provides the most responsive touch for the highest levels of play. This is because it is a simple matter to re-inflate a soccer ball not to mention the fact that most competitive leagues will have numerous balls on hand. If touch and responsiveness are your key bladder attribute, there is no other material better than latex.
Elements of the football that today are tested are the deformation of the football when it is kicked or when the ball hits a surface. Two styles of footballs have been tested by the Sports Technology Research Group of Wolfson School of Mechanical and Manufacturing Engineering in Loughborough University; these two models are called the Basic FE model and the Developed FE model of the football. The basic model considered the ball as being a spherical shell with isotropic material properties. The developed model also utilised isotropic material properties but included an additional stiffer stitching seam region.
The Futsal ball is typically smaller, harder, and heavier, allowing for less bounce and better control on harder surfaces. Senda Athletics is the official ball partner of U.S. Youth Futsal and the Vitoria is the Official Ball of the USYF League. Accented with bright red or green and created with fair trade practices, its stamp of "Respect," "Joy," and "Community" expresses the company's philosophy.
Of course, no one should truly expect this ball to be made for an organized league game since its primary selling point is that it glows in the dark. This soccer ball features two red LED lights that are powered by the same kinds of batteries used for watches. Even better, the batteries themselves are easy to change out and even have a specialized tool to assist in doing so. To prevent the batteries from running out too quickly, the ball is kick-activated and stays lit for 40 seconds.
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
