This is a felt cover ball, which is the major characteristics of an indoor soccer ball. Durable felt cover offers the softness and helps to control the rebounding characteristics. This is a size 5 ball with hand stitched panels. Hand stitched panels are more durable than machine stitched panels. The bounce is not too high, which should be the case of a standard indoor soccer ball.

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.
Another imprint you’ll find on your Adidas 2016 MLS Official Match Ball, is the FIFA quality seal. As you recall, the FIFA testing involves many aspects of testing in order to pass certification and earn this imprint. This ball passed in all categories including circumference, sphericity, rebound, water absorption, weight, loss of pressure, and shape/size retention.
During the 1900s, footballs were made out of rubber and leather which was perfect for bouncing and kicking the ball; however, when heading the football (hitting it with the player's head) it was usually painful. This problem was most probably due to water absorption of the leather from rain, which caused a considerable increase in weight, causing head or neck injury. By around 2017, this had also been associated with dementia in former players.[8][9] Another problem of early footballs was that they deteriorated quickly, as the leather used in manufacturing the footballs varied in thickness and in quality.[6]
When I buy a soccer ball at a local store, how do I know if I am buying a good soccer ball?  Ball material information on the packaging of the balls is minimal at best. Marketing hype is hard to understand. So people are very frustrated when buying soccer balls for their clubs, teams or own use. Parents of soccer players have always asked me about what type and where to buy soccer balls for their up and coming star. "Go to the local store and pick out one that is on sale" I would tell them. The only recommendation I could make was to check out soccer balls that I previously used and knew they were good quality. 
8. Major League Soccer is the top flight of professional soccer in the U.S. and so no surprise that the league’s official ball, the adidas 2018 MLS Glider Soccer Ball, is a big seller. Fans see the ball in all MLS matches and young fans aspire to one day be kicking the ball in a competitive match. Fans also take the ball to kick around before matches while tailgating with younger fans grabbing one to get player autographs.
Update (2 years post-purchase): Still love this ball and it's in its fifth season of use! I've just ordered another for our team since the fall season makes for darker and darker practices on our unlighted scrimmage field and we've come to rely on this ball so much. My teenagers use this ball at home all the time, including playing "soccer tennis" on hard surfaces and for banging against a brick wall (all of the print is long gone from the outer surface). We even took it to the beach this year. It never fails to get a reaction from people who see it bouncing around in the dark. I did have to replace one of the two lights, but they're available from GlowCity and are very reasonably priced (I purchased a couple of extra lights, just in case). I also bought a pack of 100
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.
Adidas says its design was motivated by Russia's urban landscapes. It uses textured graphics and a metallic sheen to bring a modern look to the classic design. The ball is made of six panels of thermally bonded TPU and about 15% silicone. The materials allow for better trajectory, accuracy, responsiveness, and low water absorption. It also feels well-padded and slightly lighter than previous match balls.
