Machine stitched paneling and the nylon wound carcass helps to mold the shape that is inflated to a perfect circle due to its butyl bladder, which maintains its structure at all times. Using an abrasion resistant TPU exterior, the ball retains its style no matter where it is being played with. The synthetic panels are strong yet comfortable on the side of feet making it a terrific ball to practice skill-building.
Soccer balls come in different variants and choosing one that is right will depend on how you prefer your ball and how you would like to use it. Soccer balls are built of different materials mostly made out of common rubber, polyurethane, nylon or polyvinyl chloride. While polyvinyl chloride balls can get really durable, they may not be as soft and touch responsive as polyurethane blend balls.
Another type of soccer ball that some players may find to be useful is the indoor soccer ball. Indoor balls are designed to have less bounce and rebound to them, making it possible to control the ball on a tighter court or field. The cover of an indoor ball is also the strongest of any category, so it can withstand play on turn, hard court surfaces, and impacts with walls.
You just can’t avoid the name of Lionel Messi in the soccer world anymore!  And with this ball, Adidas promises to make you like Messi.  Like the last ball, it has a nylon interior and is machine stitched.  It also has a butyl bladder so that it retains air better.  While this ball is surely a good option, it is a little pricey.  The name alone probably drives it up, but if you’re a Messi fan it may well be worth it to you!  And oh, it also looks like a ball from Pokemon!
Why do some soccer balls get bigger over time?  Many soccer balls do tend to get larger over time. Especially lower quality balls! This is due to the pressure of the bladder against the linings and cover.  Over time the material and stitching may stretch out causing the ball to become larger. Also, soccer ball abuse may cause the stitching to loosen and the ball to expand.
When I buy a soccer ball at a local store, how do I know if I am buying a good soccer ball?  Ball material information on the packaging of the balls is minimal at best. Marketing hype is hard to understand. So people are very frustrated when buying soccer balls for their clubs, teams or own use. Parents of soccer players have always asked me about what type and where to buy soccer balls for their up and coming star. "Go to the local store and pick out one that is on sale" I would tell them. The only recommendation I could make was to check out soccer balls that I previously used and knew they were good quality. 
This is much like the kind of balls that I often buy and play with.  This is a training ball, but don’t let that fool you into thinking that means it is low quality. It is machine stitched, meaning it is mass-produced and has a nylon interior, making the ball last a long time as you practice and do your daily drills.  It also has a butyl bladder and is polyurethane so that it will stay inflated longer.  It has a really catchy green and black design and I’m sure all the kids would absolutely love to have this ball (or two) for the great price!
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
