During the 1900s, footballs were made out of rubber and leather which was perfect for bouncing and kicking the ball; however, when heading the football (hitting it with the player's head) it was usually painful. This problem was most probably due to water absorption of the leather from rain, which caused a considerable increase in weight, causing head or neck injury. By around 2017, this had also been associated with dementia in former players. Another problem of early footballs was that they deteriorated quickly, as the leather used in manufacturing the footballs varied in thickness and in quality.
Update: While this ball was ruined in 3 days of use, the customer service team contacted me quickly and offered to send another product to try from this company. I thought this was very generous and warrants another try. With 3 kids now in soccer, I will update this review upon receipt of the next ball. (I added a star to the rating because they seem to want to stand by their company.)
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.
Size 5 is the official size for professional matches. Therefore, this ball is only available in this size. Do not use this soccer ball on concreted areas. Its unique rubber uses Puma Airlock Valve Technology (PAL) in order to facilitate proper airlock technology. This ball features Perimeter Balance Technology (PBT) which enables it to maintain impressive flight characteristics. https://www.youtube.com/watch?v=j2Xn84L3Kcs
