  • Patent number: 7150690
    Abstract: A soccer goal pad comprises an integrally formed foam body for overlying the playing surface of a goal post. The pad is self retained on the post. The goal pad provides impact-cushioning along the playing surface so as to reduce the risk of injury, while minimizing its affect on the trajectory and speed of a soccer goal bouncing off of the padded post. A method of making the goal pad is disclosed.
