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.[4] Some premium-grade 32-panel balls use non-regular polygons to give a closer approximation to sphericality.[12] 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.[5] 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.
Whereas plenty of manufacturers that we reviewed opted to go with a soccer ball that was more durable than responsive, Mikasa takes the opposite approach and focuses primarily on the touch that their ball can provide. This is most apparent in the soccer ball’s choice of casing material. The synthetic leather casing of the Mikasa is by far the softest and naturally responsive-without the inclusion of texture-out of any other soccer ball we reviewed. https://www.youtube.com/watch?v=3OKagE2ZIRA
