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.
I bought this ball for a non-traditional use: my miniature donkey LOVES to roll and toss balls, and slightly deflated soccer balls seem to be easiest for him to grab. We've had this one for several months now, and it has withstood his rough play extremely well. In fact, I'm back to buy another so we have a backup in case our first gets lost. I definitely recommend!
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.
What size soccer ball should I buy? The first step in purchasing soccer balls is determining the proper size(s) to buy. Many soccer leagues have different size requirements, so be sure to check with your coach or organization to find out which size ball to buy.

Everything an inexpensive, real soccer ball should be. This Wilson was significantly better-constructed, heavier and more durable than I expected it to be. Every purchase, quality-wise, must be weighed against price. And for less than $10, this sucker will last you a LONG time. I bought it for my 2-year-old. This will be the size ball he uses until he's 8 or so. Assuming he wants to play soccer. Oh dear lord, please have him want to play soccer. Come on. I need this!
Inflate soccer balls to the pressure of 6-8 PPI (pounds per square inch). A pressure gauge will tell you when the air is enough. Under or over-inflating a soccer ball will shorten its life in one way or another. When under-inflated, the ball will not be resistant to the impact of kicks. On the other hand, over inflation will stretch out the bladder and put pressure on the panel stitches.
These are used in international level matches and top league matches like UEFA Champions League, Italian Serie A, English Premier League, Spanish La Liga, Bundesliga, Major League Soccer. Not only these but also all the tournaments approved by FIFA. So you can easily understand that these are the highest quality balls with the highest level of air retention, shape, water absorption, trajectory, curve, and performance. Otherwise, FIFA would not have approved these balls.
