The Obsidian 5 has trademark graphics paying tribute to the USA national team. It is a prestigious soccer ball to add to your soccer equipment if you love buying anything US. The material used is 12% EVA, 13% polyester, 15% polyurethane and 60% rubber. These top-quality materials ensure great performance and excellent ball control to help improve your playing skills in the field. The material is durable enough to handle day to day use, and machine-stitched construction reduces water absorption while equally ensuring durability. It has a rubber bladder that enhances air retention and shape.
As an avid soccer player and coach, I know it is important to have a suitable ball. First off, this ball arrived fully inflated, which is always a plus. This way I don't have to run around trying to find a pump and needle in order to inflate it. My toddler immediately started kicking it around the house once I was able to get it out of the package! I also love the feel of this ball. It is easy to grip and allows for easy ball handling. The colors are perfect, too. It is a little boring to play with a ball whose colors are dull or faded. The contrast between the blue and electric yellow is perfect. The colors make the ball easy to see.
I’m playing soccer since I was 10, since 2005. I have also played it before, but I was not so serious as after. At the age of 10, I started to practice it seriously. Now I’m still playing it. During my career, I have tried, changed and played with many different soccer balls. Because I have tested so many of them, I have also created my top best soccer balls which you can see below.
When it is about quality, these are almost same as premium match soccer balls but obviously not the same. To be exact, you can say official match soccer balls are positioning between premium match balls and training soccer balls regarding quality. That means these balls also offer an excellent level of air retention, shape, water absorption, curve, and performance. Although usually, they are not as durable as training balls but as a whole, they are very much durable.
Best of the Rest – The World Soccer Shop Heritage Ball was designed to have a vintage look with the 18 panel, brown leather design. It probably won’t feature in any competitive matches but is a great all-around ball for a casual kickaround. As the official ball of the NCAA it is not a surprise that the Wilson Avanti NCAA Official Championship Soccer Ball is a top seller.
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.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
