Latex bladders are used in high-quality balls. These kind of bladders are soft and provide good feeling. They offer better response and bounce than Butyl bladders, but the downside of this kind of bladder is they don’t hold the air for too long. As a result, they require filling more frequently. Air escapes due to micropores on the cover, but nowadays some balls are constructed with carbon latex bladder to help to close these micropores. As a result, the balls can hold air for a longer period.
For those taking their game to the next level, it’s important to train with a ball similar to what is used for your matches. Your passing, shooting and general foot skills will be different for lighter soccer balls made with a premium bladder like latex. Try out an NFHS approved ball which is used for some club, high school, and college teams. To be NFHS approved, the soccer ball needs to:
Changes in temperature will also affect the inflation level of the soccer ball. Extreme heat or extreme cold will alter the shape of the bladder and this will affect the integrity of the soccer ball. Although it doesn’t seem like you could reach an extreme temperature that could do this to a soccer ball, just leaving a ball in your trunk or the back of a van on a hot Summer’s day will do it.
As always with Nike balls, the Merlin has an excellent feel, particularly when passing. The ball is also great for shooting due to Nike’s 4-panel construction, 360-degree sweet spot technology and the soft polyurethane outer material. It won’t deviate too much in the air due to the thermally-bonded pentagonal panel layout, so it’s perfect for training as well as games.
I have about 30 soccer balls- price listed is per ball. I have more than the 12 pictured- some doubles of the champions league balls, two of the unwrapped Brine ball, 5 or so futsal balls. Some are worth more than 25, some less. Just make me a good off and tell me which ball you want! Keep in mind when you offer that I am paying most of the shipping already. Balls will ship deflated. I will reconfirm that all hold air and make sure they are cleaned off before shipping. There is only one ball in the lot that has a gouge/ panel issue. All aside are in good playable shape.
On the other hand, replicas (sometimes called training balls or gliders) are designed to be just like the official match balls but are much cheaper. Their panels are often stitched rather than thermally-bonded and are made of a different material. However, they’re not necessarily less durable than official match balls. So, they’re the recommended option for most players.
