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.
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.
I decided to try to contact Kan Jam, since I was more interested in the possibility of an exchange than a return. In my experience, if a company will honor an exchange, some of the time, they won't require that you send the original product back. But I couldn't find any direct contact info for Kan Jam and decided to just open up a Return Request through Amazon. I did say in the comments that I would prefer an exchange over a return, but I
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.

8. Major League Soccer is the top flight of professional soccer in the U.S. and so no surprise that the league’s official ball, the adidas 2018 MLS Glider Soccer Ball, is a big seller. Fans see the ball in all MLS matches and young fans aspire to one day be kicking the ball in a competitive match. Fans also take the ball to kick around before matches while tailgating with younger fans grabbing one to get player autographs.
Some additional information worth noting with this Adidas smart soccer ball is that you cannot use the sensor features for kicks once the ball is in motion. Users report you cannot use it for tracking stats associated with, for example, a drop kick. The ball must be sitting still on the ground before being kicked if you wish to track the statistics.
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.

Excellent texture for a size 4 ball. I purchased this ball for my son who is playing in a U9 team. It's soft and many kids like this ball. On home games it is our game ball. It arrived properly inflated and 2 months later, I still have not had the need to add air. Expect faster wear and tear if your kid plays on concrete. :( I would recommend this ball.
The soccer ball has gone through various changes just as the football game. As opposed to yesterday’s football ball that had stitches and seams and the classic black and white design, today’s soccer balls are designed with the latest technology that lets the ball bend more, fly quicker and also dip harder. Besides, they are quite soft that they let players kick the ball further without risking injuries. https://www.youtube.com/watch?v=DGp37du0xbQ
