Soccer balls in the 1870's were made by stitching segments of leather together.They were heavy and hard to kick. The balls could kill some one if they were headed.
In the 1940's they made balls lighter and easier to kick. This made it safer to head the ball. In the 1930's leather shin pads were now being worn inside socks. The shoes were also made with laces instead of buckles.
But now we use light weight plastic shin guards instead of leather. We use flexible light weight cleats. In conclusion soccer has had many changes throughout history.
