What sets each soccer ball apart from another is the quality of the materials that are used in its construction. The lining, bladder, cover, and the quality of the overall craftsmanship will all influence the final cost of the soccer ball you’re looking at. Higher quality balls are usually bonded together to provide a superior shape retention experience and offer a truer flight.
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
