Great replica soccer balls! My kids love them. So much so, they are waiting until the fall when their new season starts to "keep them nice." They are authentic Adidas, and even come with the FIFA reflective sticker to place once the ball is inflated. Side note: The balls do arrive flat, so make sure you have a good pump with separate gauge as not to over inflate.
This is a great way to find additional information about the ball. When I’m buying online I always look if I can find something like this. Just take a look at that and you will for sure find extra information. When you are buying local this is a little bit harder, but you can still ask the vendor or somebody that has already bought that or similar ball in that shop.
The soccer is the world's most popular and widely watched game. Due to increasing technological advancement and demand for performance, the ball manufacturers have been developing new designs progressively. A traditional spherical football made of 32 leather panels stitched together in 1970s has become only 14 synthetic curved panels thermally bonded without stitches ball in 2006 and more recently 8 panels football in 2010. Despite being most popular game in the world, scan data is available on aerodynamic properties of footballs especially Jabulani, Teamgeist and Fevernova balls. The primary objectives of this study were to evaluate aerodynamic performances of these three soccer balls. The aerodynamic forces and moments were measured experimentally for a range of wind speeds. The aerodynamic forces and their non-dimensional coefficients were determined and compared.
These soccer balls are exact replicas of the finale game balls, right on down to the specific design details that can be found on the ball. If you’re looking for a durable, reliable ball that can help players replicated the feeling of playing the game at home, then the Top Training Series by Adidas is one of the best options to consider today. Each ball is guaranteed to pass FIFA tests for weight, circumference, rebound, and water absorption. It is the closest you can get in the entry-level categories for a soccer ball to the match ball experience. https://www.youtube.com/watch?v=3OKagE2ZIRA
