The downside? They’re expensive. Like, really expensive, depending on which one you get. Whether you really need one depends on your budget and how you’re going to be using your ball. For example, I use official match balls for practicing freekicks because they fly through the air really nicely. However, I don’t use them for training because if I lose my ball I’ll be set back $100-$300.
The type of soccer cleats or indoor shoes needed depends on what kind of field your child’s team will be practicing and play on. Have your child try on Firm Ground cleats with hard rubber or plastic studs if playing on a pitch made of natural grass or on well-worn artificial turf. Look for Artificial Turf shoes with a super low profile and an outsole evenly covered all-over in small rubber studs for the best traction on an indoor or newer outdoor turf surface.
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.
This is a great way to find additional information about the ball. When I’m buying online I always look if I can find something like this. Just take a look at that and you will for sure find extra information. When you are buying local this is a little bit harder, but you can still ask the vendor or somebody that has already bought that or similar ball in that shop.
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
