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.
This time there is no stitching to attach the panels, but they are thermally bonded. This is the interesting part. First, we wanted to see how it performs in the air for a free kick. You will find a decent, predictable trajectory. Although when you are knuckling, the result mainly depends on your skill and the air direction, a ball plays a vital role as well to help your process of a successful knuckle shot.

Update: While this ball was ruined in 3 days of use, the customer service team contacted me quickly and offered to send another product to try from this company. I thought this was very generous and warrants another try. With 3 kids now in soccer, I will update this review upon receipt of the next ball. (I added a star to the rating because they seem to want to stand by their company.)

Voit goes a way back since its foundation in 1922 in providing the best soccer balls to all soccer fans and professional players. By the end of the 1920, the company introduced the first fully molded rubber soccer ball. They also came with the needle like air retention valves. They later invented a technology that allowed the balls to be machine wound with sturdy nylon threads over the rubber bladder. This ensured that the soccer balls would be stronger and more consistent. It also made balls cheaper and more available since they can be produced in mass production.
This is a size 5 ball that can withstand an intense practice sessions and heated soccer matches. It has the highest FIFA rating which assures its users of its quality. To further ascertain its quality, this match ball has passed through a series of tests. These check to see whether its weight, shape, water uptake, and size retention are up to par. The casing uses PU and panels are hand stitched which sees to it that the ball holds together match after match. The latex bladder facilitates its high rebound characteristics.
If you're headed to the park to play a quick pickup game, brightly colored adidas soccer balls can help make it easy to distinguish your match from other games that might be being played nearby. Dribbling skills conducted with mini Nike soccer balls can hone your control skills, so you can glide past defenders with ease. Look for 12-panel soccer balls that provide a true, accurate flight with each strike, and rubber butyl bladders that offer excellent shape and air retention, so you can quickly jump into a game without looking for a pump. If you prefer playing indoors, check out a futsal ball that's slightly smaller than regulation soccer balls and is designed for use on hard indoor courts.
Update (2 years post-purchase): Still love this ball and it's in its fifth season of use! I've just ordered another for our team since the fall season makes for darker and darker practices on our unlighted scrimmage field and we've come to rely on this ball so much. My teenagers use this ball at home all the time, including playing "soccer tennis" on hard surfaces and for banging against a brick wall (all of the print is long gone from the outer surface). We even took it to the beach this year. It never fails to get a reaction from people who see it bouncing around in the dark. I did have to replace one of the two lights, but they're available from GlowCity and are very reasonably priced (I purchased a couple of extra lights, just in case). I also bought a pack of 100
This is one of the best and most affordable soccer balls from Mikasa. Expect high performance without having to spend a fortune for it. For a training soccer ball, this one is quite soft hence ideal for foot dribbles and head-butting. This is due to its soft composite cover and the unique machine stitching panels. This is a factor that facilitates control for younger players. A keen look will tell that younger players usually find difficult to control hand-stitched soccer balls. It is available in three sizes; 3, 4 and 5 hence friendly to different users and different functions. The double stitching on the panels adds life to it as makes it more resistant to tear.
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
