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.
When it is about quality, these are almost same as premium match soccer balls but obviously not the same. To be exact, you can say official match soccer balls are positioning between premium match balls and training soccer balls regarding quality. That means these balls also offer an excellent level of air retention, shape, water absorption, curve, and performance. Although usually, they are not as durable as training balls but as a whole, they are very much durable.
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. https://www.youtube.com/watch?v=j2Xn84L3Kcs
