The shin guard is used to protect the shin bone, and is also called the shin guard. Due to the high antagonism of the football game, the probability of a player being kicked to the calf is very high, so it is very necessary to wear a leg guard that is suitable for you to protect your shin during the game. From a physical point of view, the shin guard is to disperse and cushion the impact that would otherwise be applied to the calf. The gap between the leg shield and the leg can play a buffering role, and the skin between the leg bones and the leg shield also has a buffering role to prevent fractures.
