Only size 5, and size 4 are available for this. Although this should not be a major problem as this is for recreational play and practicing purpose, so kids are ok to play with this as well. In fact, the ball that will be given away to the developing countries will be used by the kids mostly. If you are buying this for an adult go for size 5, and if you are buying for kids or youth players then better go for size 4.
You have to wonder if a brand recognized mostly for baseball can make a good soccer ball, but this one seems like a worthy effort. It certainly has the look and feel of a high end ball, and the overall build seems pretty solid. It looks like they put some effort designing this product. My son and his team practiced with this several times and I would say the wear and tear look normal. No tearing at the seams or unusual gashes. He says the padding gives the ball a nice, soft touch even when fully inflated. One bonus is, with such an uncommon soccer brand, it easier to identify if it gets lost on field. The reason for the lack of 5 stars is that our sample has trouble holding air after a couple of days. I do not know if it is a characteristic of the ball or
Why do I always have to pump up even expensive balls? Many balls use bladders made out of latex. Natural Latex Rubber bladders offer the softest feel and response, but do not provide the best air retention. Micro pores slowly let air escape. Balls with natural rubber bladders need to be re-inflated more often than balls with butyl bladders. Even after one or two days, the latex bladder will leak enough air so that you will have to inflate the ball back to recommended pressure. Some balls use carbon-latex bladders in which the carbon powder helps to close the micro pores. Soccer balls with carbon latex bladders usually increase air retention to approximately one week. Of course, check the ball for punctures that may cause the air to leak out.
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.
