This is a decision being made by a league operator or manager of some sort, this section is important for you.  For the individual, there isn’t much of a determination here.  If you want something really nice like the pros, go premium.  But if not, then you probably will just want to go with a training ball.  But for people equipping their teams with materials, this is a decision that needs to be taken seriously.  I would suggest that recreational leagues stick with training match balls, even for matches.  The number of kicks that the ball will get and the improper technique will cause headaches for you if you decide to buy premium balls.  For high schools, I suggest just regular match balls as many are still learning the basics of the game and many teams simply play “kickball” at that age.  For college teams, semi-pros, serious travel clubs, and of course, professional teams, I suggest premium match balls for play!

In 1937, the regulation soccer ball put on a little weight, increasing from 13-15 ounces to 14-16 ounces. Soccer balls used to be made exclusively of leather. Not so these days! Current technologies have come up with leather-like synthetic materials that are softer, more lightweight, water-proof, and perform as well if not better than leather soccer balls. As for the look, early soccer balls were tan but difficult to see from the stands; although white leather-washed soccer balls are known to have been used. White soccer balls replaced their tan predecessors in the 1950s, and were composed of 18 panels. Black spots were added to allow soccer players to track the ball's swerve. Today's soccer balls come in an array of colorful designs and styles to suit every player.

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.
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.
