Nike Mercurial Hard Shell Football Shields. The flat plate is attached to a solid base that spreads the load evenly across the surface. High-quality holders provide reliable and comfortable fit shields. The low-profile design reliably protects the legs throughout the game, without interfering with the athlete. Football pads can not completely eliminate injury, but, if used properly, can prevent superficial damage. These flaps are designed to protect against both bruises and scratches in case of inevitable hits during a football game.
