Built for durability, recreation balls are made of soft synthetic materials for play on nearly any field. Typically, these balls are slightly heavier for beginner’s slower play, yet, competitors of all skill levels use these balls for practice and recreation on hard turf fields due to their resilience. Machine-stitching is the most stand-out visual difference between match balls and training balls and it offers a consistent touch for any player.
It depends on its intended use. Soccer ball casings are made from three kinds of synthetic materials. Polyvinyl carbonate (PVC) which is what most less expensive training balls are made from, Polyurethane (PU) which is the preferred ball for soccer tournaments, and a combination of the two. There are also foam and rubber training soccer balls for kids. Some kids' soccer balls are made of 100 percent thermoplastic polyurethane (TPU), which is a kind of foamy casing material so the ball is very soft. There are greater and lesser grades of each kind of material. PU-covered balls are generally softer, livelier, and have a better feel to them, and are what most people seek when looking for a optimal performing soccer ball.
The exclusive design of the exterior hides a football manufactured in specially-developed Japanese TEIJIN microfibre, which makes the ball seem significantly softer than its predecessor. Without compromising on material thickness or adding foam, we have achieved a thoroughly tested feeling of liveliness and lightness – while naturally also preserving the good characteristics such as control and stability that have always characterised a BRILLANT SUPER.The material may be Japanese but BRILLANT SUPER is produced as always by our year-long supplier in Pakistan. The ball is sewn by hand and produced in quality materials from its innermost to its outermost layers. The Zero-Wing bladder ensures that the ball remains in constant balance throughout its flight through the air and a Double-Lock butyl valve ensures that it is practically airtight.​

Rounding out our list is just a good old, cool-looking training ball from the people over at Puma.  This ball comes will three distinct colors on it.  Black is in the middle of pink and yellow, so this would be an absolute dream for the soccer-loving girl in your life!  It is machine stitched for durability and a very soft feel.  It holds up for extended periods of time and does so starting at a very low price, so take a look for yourself!
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.
Sizing is very important in selecting a soccer ball.  For the purposes of this article, I will mostly concentrate on size 5 outdoor soccer balls, but I will quickly go over the various sizes and let you know what they are used for.  Size 1 soccer balls, or skill balls (also known as mini balls), are primarily used by youth players that are just being introduced to the game.  These are typically 1-3-year-olds.  Another use for Size 1 balls is for older players to learn to juggle.  It is much harder to juggle a size 1, so instead of using a hacky sack, they use a skill ball.  This is done because the texture and materials are similar.  Size 3 balls are slightly bigger than size 1 and are used for ages four through seven.  They do this so that the ball isn’t too big in comparison to the players.  Size 4 balls are used for age eight through eleven.  Size 4s are smaller than size 5, which is used for everyone past the age of eleven.  This is the same size that the professionals use.  Making sure that you have the proper ball is just as important as picking out which materials one has.
I purchased the Knuckle It Pro soccer ball for my sons 12 th birthday in August of 2017. When I asked what he would like for his birthday he had mentioned this ball. I had never heard of it so I began doing research on the product. We had at least 4 soccer balls at home at the time so I wasn't sure I'd go with another ball. We have one of nearly every major brand ranging in price from $15-30. He had even received a $40 ball just months before for Christmas so I really didn't see the point in one more.
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
