It depends on its intended use. Soccer ball casings are made from three kinds of synthetic materials. Polyvinyl carbonate (PVC) which is what most less expensive training balls are made from, Polyurethane (PU) which is the preferred ball for soccer tournaments, and a combination of the two. There are also foam and rubber training soccer balls for kids. Some kids' soccer balls are made of 100 percent thermoplastic polyurethane (TPU), which is a kind of foamy casing material so the ball is very soft. There are greater and lesser grades of each kind of material. PU-covered balls are generally softer, livelier, and have a better feel to them, and are what most people seek when looking for a optimal performing soccer ball.
One of the top brands recommended by coaches, Adidas has a large line of fantastically designed soccer balls available in just the right size for your little one. The Ace Glider II is the perfect way to give your child a soccer ball that not only lasts but also shines on the field! The unique colorings of this ball make it visible from a long distance away, giving you a great way to spot your little one against others on the field. Not just a pretty face, the Glider II is also a sturdy and well-constructed soccer ball that utilizes top-quality materials for long-lasting play. The cover is made of durable TPU material that has been built to withstand daily practice and can handle both indoor and outdoor play. Unlike similar balls that tend to develop blisters over time, this ball uses heavy machine stitching that can significantly extend the life of the ball.
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
