A plastic helmet as in other sports would not suffice since they are bulky and may consist of uneven surfaces; this would make ball control off a header nearly impossible.

The softness of the foam will increase the time of impact and lessen the blow without altering the direction and distance of the ball as it rebounds off the head.〔〔("Soccer Headgear Fails Impact Tests" ).
