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.
Premium Match Balls. These are the most expensive soccer balls that you’ll find on the market today. They are FIFA-approved balls, so they meet all of the standards necessary for international play. Air retention, water-resistance, and performance are far superior when compared to a training ball. Virtually every professional league uses a ball of this quality for game play.
A tribute to one of the richest teams in the world, Paris St. Germain, this ball is dressed in their colors.  This is a ball meant for everyday use, so you can get out there and show off your favorite club to everyone.  It is made from polyurethane and has some polyester inside of it, making it slightly different than the Messi ball.  The polyester buttresses the butyl bladder, causing it to retain air and shape.  It is machine stitched and has 26 panels, so it may take a little bit of getting used to the first time.  Like the Messi ball, it comes at a pretty steep price, so it may be a little pricey if you aren’t a PSG fan!
This type of ball is easy to distinguish because its outer material is similar to the material used on tennis balls. They normally are a size 5 and similar to the outdoor soccer ball. Indoor soccer balls are purposely designed with less rebound in order to accommodate turf and harder surfaces that cover the walls of an indoor soccer field and playing ground.
Outside of PU and TPU, pretty much every other material used for a soccer ball’s casing will be specialized for either durability or responsiveness. When it comes to synthetic leather, the focus is also exclusively on responsiveness and this is by far the most responsive material used for a soccer ball’s casing. It is important to note that PU, TPU, and PVC are all often labeled as synthetic leather.

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.

 As an International Match Standard and NFHS (high school) and NCAA-approved ball, this one gets a lot of play out of high schools and colleges in the United States.  And for good reason.  Every time I played with a select ball, I knew what to expect and I got each and every time.  Coming in a number of colors, this ball can be tailored to match your team while still looking classy with the white to contrast it.  It has a latex bladder and is hand-stitched.  This is a premium match soccer ball for the price of a practice ball.  Definitely a ball to consider looking into.
Soccer — or football as it's known around the world — is arguably the most loved sport on Earth. Although Americans still aren't as enamored of the sport as the rest of the world is, teams around the country are stealing hearts and minds, and Americans are getting into the game. For years, soccer has been a sport played by kids, college students, and ex-pats, but it's now being cheered in stadiums and watched on national TV.
