In the year 1863, the first specifications for footballs were laid down by the Football Association. Previous to this, footballs were made out of inflated leather, with later leather coverings to help footballs maintain their shapes. In 1872 the specifications were revised, and these rules have been left essentially unchanged as defined by the International Football Association Board. Differences in footballs created since this rule came into effect have been to do with the material used in their creation.
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.
I’ll be honest right out of the gate in saying that I don’t have any experience with Senda. But after looking at this ball, I will have to try one out soon! Senda brings a very classic look to its ball, giving you a throwback to days gone by. It has 32 panels and claims that it can be used outdoors, indoors, and on turf. It is hand stitched with premium leather and has four layers of hybrid polyester and cotton linings between the cover and the bladder to help it last longer. It is NHFS approved with its latex bladder, so it would be great for use in high school matches. And especially considering it’s low cost.
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
