Soccer ball covers are meant to protect the construction of a ball, and make it more durable and long lasting. Manufacturers use two types of materials, mainly polyurethane (PU) or polyvinyl carbonate (PVC). PVC is the cheaper and much affordable variant, but it is more durable than PU. It has scuff-resistance, which makes it perfect for training soccer balls. PU is used for match balls, since it is softer than a PVC soccer ball and tends to respond better to contact.
Due to it being significantly softer than the other types of rubbers used for soccer ball bladders, latex is generally seen as the premier material. Though, this same perception may not hold as true for practice balls or even game balls at lower levels of competition. This is because latex bladders retain air worse than all of the other soccer ball bladder materials and will need to be re-inflated more often.
Training balls are ideal for training and recreational use. These are the least expensive and more durable compared to professional match balls as they are meant to be continuously used for an extended period of time. This type of ball is usually constructed with 4 or fewer layers. The casing is made of PVC which makes its quality lower compared to a professional match soccer ball. Usually, the panels of a practice ball are molded together and not stitched together. These type of balls can withstand rough surfaces such as; asphalt and concrete.
I bought this ball for a non-traditional use: my miniature donkey LOVES to roll and toss balls, and slightly deflated soccer balls seem to be easiest for him to grab. We've had this one for several months now, and it has withstood his rough play extremely well. In fact, I'm back to buy another so we have a backup in case our first gets lost. I definitely recommend!
Whereas plenty of manufacturers that we reviewed opted to go with a soccer ball that was more durable than responsive, Mikasa takes the opposite approach and focuses primarily on the touch that their ball can provide. This is most apparent in the soccer ball’s choice of casing material. The synthetic leather casing of the Mikasa is by far the softest and naturally responsive-without the inclusion of texture-out of any other soccer ball we reviewed. https://www.youtube.com/watch?v=3OKagE2ZIRA
