One thing which customers often complain about soccer balls is their poor air retention ability. After a few days on the field, the ball starts to deflate which serves as a big problem for anyone who has to use it on a daily basis. However, there is no such thing with the Top Glider as inside this ball is the butyl bladder which is becoming a norm with the majority of the Adidas soccer ball’s nowadays for better air retention.
From the players at the World Cup to the best clubs in the world battling it our for the Champions League title, the little round thing at the center of the field is an Adidas soccer ball. The 2014 World Cup Brazuca soccer ball became an instant winner, with the unique panel design that helps the ball fly straight, far, and accurate. The UEFA Champions League match ball features a star panel design, helping the stars on the field play at the top level. These soccer balls are considered some of the best in the world. When looking for a lower price on a match ball, the Adidas Competition soccer ball uses a traditional panel design to deliver the best touch and play. The Adidas Top Training soccer balls are perfected to help retain air and shape while taking a pounding during a touch training session. The Adidas Top Replique and Replique soccer balls perform well as a trainer or quick game. The Adidas UCL Capitano is a great ball to always have on hand for a game with friends.
Please note, there are only 3 sizes available for this model; size 5, size 4, and size 3. So it is crucial that if you are looking for size 2 or size 1, then this is not an option for you. So, choose the right size before buying so that you don’t regret after receiving the purchase. If you are not sure which size means what then click here to read our guideline.
Our main intention of finding the official match balls was to help you find a solution which is good in quality, and you can use it for league plays. The process was tough we must say. Not all the replica balls have good quality. That is why we were very choosy in the process. We filtered the balls not only based on our experience but also based on the experience of other users.

The soccer is the world's most popular and widely watched game. Due to increasing technological advancement and demand for performance, the ball manufacturers have been developing new designs progressively. A traditional spherical football made of 32 leather panels stitched together in 1970s has become only 14 synthetic curved panels thermally bonded without stitches ball in 2006 and more recently 8 panels football in 2010. Despite being most popular game in the world, scan data is available on aerodynamic properties of footballs especially Jabulani, Teamgeist and Fevernova balls. The primary objectives of this study were to evaluate aerodynamic performances of these three soccer balls. The aerodynamic forces and moments were measured experimentally for a range of wind speeds. The aerodynamic forces and their non-dimensional coefficients were determined and compared.

When any object goes through the air, a thin cushion of air wraps around it that stays relatively still. This boundary layer is why you get dust trapped on your ceiling fan. At slower speeds, the air around a soccer ball moves smoothly over the surface and separates off the sides of the ball at its widest points. Imagine a ball moving from right to left across a clock, Goff explains, so traveling from the 3 to the 9. With laminar flow, the air flows over the surface and then flows off at the 12 and 6, which creates more drag in the air. Drag slows the ball down faster. At higher speeds, the air moves turbulently across the ball’s surface and peels off at the 2 and 4. The wind effectively wraps around the back. This turbulent flow has less drag, which means the ball keeps moving at high speed for longer.
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
