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.
We found that the feeling of this ball was a bit harder than other soccer balls at this price point. This doesn’t affect the performance of the ball, as the movements were accurate and authentic when struck. The weight does tend to affect the foot and ankle over time, causing a bit of soreness after continuous play. It also features a machine-stitched construction that is accompanied by an internal nylon-wound carcass so the ball has an improved level of durability compared to other soccer balls at this price point.
In 2010, the infamous Jabulani balls for the World Cup in South Africa transitioned from turbulent to laminar flow between 50 and 45 miles per hour, right at the speed for corner and free kicks. The transition between these different types of flow causes even more drag on the ball, which caused the Jabulani to wobble in the air and drop in ways that players weren’t expecting.
On the other hand, replicas (sometimes called training balls or gliders) are designed to be just like the official match balls but are much cheaper. Their panels are often stitched rather than thermally-bonded and are made of a different material. However, they’re not necessarily less durable than official match balls. So, they’re the recommended option for most players. https://www.youtube.com/watch?v=j2Xn84L3Kcs
