With all of those accolades, you might be a bit surprised that this is only rated as the best training soccer ball we reviewed rather than the best performing. For the most part, those questions are warranted as the first two layers of this soccer ball are made out of great materials. The casing is made of TPU, which provides a solid amount of durability, but it is the lining that stands out. With both polyester and EVA, this ball is easier to kick for longer periods without suffering from fatigue.

The secret to the authentic movements on a rebound with this ball is the inclusion of an SBR foam layer underneath the PU cover. This allows the power of a pass or shot to be transferred with more accuracy. It keeps the ball somewhat soft to the touch, but creates a realistic movement which allows players to develop an ability to start reading the game with accuracy without the need to purchase an expensive premium match soccer ball. It comes in all of the standard sizes and offers 4 unique design options, allowing players of any age or ability to begin working on their soccer skills.
I’ve been a fan of soccer since I was 12, and choosing the right ball has always been an issue for me for many reasons ( size of the ball, its cover get torn easily, the ball don’t last long). this article had shed the light on everything you should take into consideration when buying a soccer ball, it was a very informative and well explained article it made me feel engrossed while reading it, so thanks for sharing. The Knuckle-it Pro soccer ball caught my attention, the features of this ball suits my needs as I love freekicks and I don’t really care about the brands. I’ll keep this ball in my mind for sure, when i consider buying a new ball.
By no means is this type of ball similar to a typical soccer ball. For starters, instead of air, its bladder is filled with foam. In this case, the ball has less bounce and is heavier in order to facilitate its purpose; meant to be used on a hard surface indoors. This size 4 ball may also have suede castings which help to stabilize the ball on a slippery floor.
How Do I inflate my soccer balls? Soccer balls lose air pressure over time. Sometimes over a few days (soccer balls that use butyl bladders keep air pressure longer than balls that use latex bladders). Be sure to check the pressure frequently to make sure the ball is properly inflated.  Therefore, invest in a good ball pump, have a supply of inflation needles and use a low pressure gauge to measure for proper inflation. 
The most modern feature is an embedded NFC chip, which is found on the top of the ball. If you download a free app on iOS or Android, you can personally interact with the ball's exclusive content and location-specific challenges. You'll also be able to participate and enter competitions and World Cup-related challenges. Of course, you can record and upload your experiences for social media posterity.
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
