When a tournament is held (like the FIFA World Cup), the sponsor of the event will design a brand new ball. These are official match balls – they’re used by professionals during real matches. They are designed to the highest possible build quality, have textured surfaces to improve stability in flight, and feature thermally-bonded panels for durability.

Footballs have gone through a dramatic change over time. During medieval times balls were normally made from an outer shell of leather filled with cork shavings.[4] Another method of creating a ball was using animal bladders for the inside of the ball making it inflatable. However, these two styles of creating footballs made it easy for the ball to puncture and were inadequate for kicking. It was not until the 19th century that footballs developed into what a football looks like today.

I decided to try to contact Kan Jam, since I was more interested in the possibility of an exchange than a return. In my experience, if a company will honor an exchange, some of the time, they won't require that you send the original product back. But I couldn't find any direct contact info for Kan Jam and decided to just open up a Return Request through Amazon. I did say in the comments that I would prefer an exchange over a return, but I
The Desafio 395 new soccer ball has UA TOUCHSKIN Technology that helps deliver a soft touch and an excellent feel when handling the ball. It is made of PU exterior material that is great for power transfer. Besides, the ball has an SBR Foam layer that adds softness for improved performance while the high rebound rubber bladder ensures excellent control and touch of the ball. It can be bought in two different sizes and selecting the best color depends on your personal preference.

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.
This time there is no stitching to attach the panels, but they are thermally bonded. This is the interesting part. First, we wanted to see how it performs in the air for a free kick. You will find a decent, predictable trajectory. Although when you are knuckling, the result mainly depends on your skill and the air direction, a ball plays a vital role as well to help your process of a successful knuckle shot.
As always with Nike balls, the Ordem IV has an excellent feel, particularly when passing. The ball is also great for shooting due to Nike’s 360 degree sweet spot technology and the soft polyurethane outer material. It won’t deviate too much in the air due to the thermally-bonded pentagonal panel layout, so it’s perfect for training as well as games.
Soccer — or football as it's known around the world — is arguably the most loved sport on Earth. Although Americans still aren't as enamored of the sport as the rest of the world is, teams around the country are stealing hearts and minds, and Americans are getting into the game. For years, soccer has been a sport played by kids, college students, and ex-pats, but it's now being cheered in stadiums and watched on national TV.
