A Futsal ball is basically an indoor soccer ball used for playing 'Futsal', a term literally meaning 'indoor football'. Futsal is a kind of soccer played on a basketball-sized court using a smaller, heavier, less bouncy ball, and demands many of the same skills as outdoor soccer. Size-wise, FIFA-approved futsal balls are just shy of 25 inches in circumference, slightly smaller than a Size 4 soccer ball. The ball is created with less bounce to facilitate indoor play.
Footballs have gone through a dramatic change over time. During medieval times balls were normally made from an outer shell of leather filled with cork shavings. Another method of creating a ball was using animal bladders for the inside of the ball making it inflatable. However, these two styles of creating footballs made it easy for the ball to puncture and were inadequate for kicking. It was not until the 19th century that footballs developed into what a football looks like today.
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
