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.
Besides just its sleek exterior, the Adidas Starlancer is crafted with longevity in mind by the nylon being wound internally and assembled through machine stitching to provide it with an extra level of strength. The exterior is made of TPU material, which is ideal for resisting cuts and scrapes. The bladder which holds the air is Butyl, which works wonders in keeping the shape of the ball perfect at all times.
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.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
