Elements of the football that today are tested are the deformation of the football when it is kicked or when the ball hits a surface. Two styles of footballs have been tested by the Sports Technology Research Group of Wolfson School of Mechanical and Manufacturing Engineering in Loughborough University; these two models are called the Basic FE model and the Developed FE model of the football. The basic model considered the ball as being a spherical shell with isotropic material properties. The developed model also utilised isotropic material properties but included an additional stiffer stitching seam region.
I bought this soccer ball for my granddaughters for Christmas. It arrived inflated, which concerned me. My husband inflated it with no problem and it is just fine. The ball is bigger than I thought it would be, but that is because it is a size 5 and the girls use a size 4. I didn't see the different sizes when I ordered it. It does light up very nicely and the girls love it. They got outdoor soccer nets for Christmas and I thought this ball would be great as they play late in the day. They can't wait to put it to use.
Today's footballs are more complex than past footballs. Most modern footballs consist of twelve regular pentagonal and twenty regular hexagonal panels positioned in a truncated icosahedron spherical geometry. Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality. The inside of the football is made up of a latex bladder which enables the football to be pressurised. The ball's panel pairs are stitched along the edge; this procedure can either be performed manually or with a machine. The size of a football is roughly 22 cm (8.65 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm in circumference. Averaging that to 69 cm and then dividing by π gives about 22 cm for a diameter.
This ball has been through all of the hazards that kids can dream up. Dribbling the ball on pavement walking to the car, practicing shots against a brick school, being used as a seat, heavy use at practice, and its frequent selection as the game ball. With all of that, it still looks great with very little wear and tear. Could still pass as a new ball from a few feet away. It's held it's pressure very well. The outer shell texture allows good grip without being to soft or too hard.
The ultimate determination is how a soccer ball feels and performs for you on contact. A good soccer ball will not only be tough enough to hold up to your fast and furious play, it will feature a soft casing for comfortable heading, and durable stitching (if stitched). It should handle well, and have good response. Most good soccer game balls feature a poly-urethane (PU) casing. Most leagues prefer 32-panel designs for its performance value. Also check for a warranty. Your new soccer ball should come with a manufacturer's warranty against defects and damage caused by normal play.
Soccer balls also have various sizes that you can choose from, and what is best for you will depend on how old you currently are. Soccer balls come in different constructions in the inner bladder and the lining, which can contribute to their responsiveness on the field. Panels on a soccer ball are also important since they can influence a ball’s flight characteristics, and the control a player will have on the field. Like any other sporting equipment, picking the right soccer ball, if you are very meticulous, is something that will need some key points to consider.
This soccer ball is specifically designed for indoor play. It features a foam backed casing that makes it just right for the indoor play. This fabric also facilitates skills developments for young players. It is the perfect ball for training and recreational play. This is a safe indoor soccer ball for young kids as the outer fabric provides a soft padding upon impact. Instead of air, this ball is foam filled which makes it a durable choice. This also means that the ball requires less maintenance since no air re-fill is required. The foam interior makes this ball safe, especially for its intended target users. The impact is cushioned hence young players can use it to practice for dribbles and head-batts. The fact that there are no chances of injury with this ball adds to its appeal.
There are several different materials and methods of construction used in soccer balls. Typically, Polyurethane casings are preferred as they’re often seamless and thermally bonded for premium play and long-lasting durability. However, many of the hand-stitched options are also very durable. The least durable options tend to be lower in price and machine stitched.
You may be worried because you feel it sells too expensive but this is not the case. With all these great features, the ball still ranks as an affordable ball. It features a machine-stitched construction with internal nylon wound carcass that ensures maximum durability and long-term performance. Further, the TPU material used on the exterior will resist abrasion, and the butyl bladder provides best air retention to keep it in shape and remain inflated for a long time.
Due to it being significantly softer than the other types of rubbers used for soccer ball bladders, latex is generally seen as the premier material. Though, this same perception may not hold as true for practice balls or even game balls at lower levels of competition. This is because latex bladders retain air worse than all of the other soccer ball bladder materials and will need to be re-inflated more often.
This is a very special soccer ball which I’ll think you’ll fall in love with. At least that was the case with me. I must say that I don’t normally trust new comers in the industry of soccer equipment. I mostly prefer established companies like Adidas, Select or Brine. However, the guys at Bend-it (the company behind Kunckle-it) really changed my perspective.
