Pre-wrap is pre-taping foam underwrap designed to help protect skin from tape chafing and sticking. Pre-wrap is put on before athletic tape. It can be used to hold pads and socks in place and as a protective wrap inside hiking boots, ski boots, and other athletic footwear. The foam is velvety-soft and clings to itself, but doesn't stick to other materials.
Pre-wrap is used by athletes everywhere. It's especially popular with female soccer players, due to strict regulations on hair accessories. No need to worry about headbands that are too big or too small. The foam isn't sticky but stays in place! We don't really know the origin of using it as a hair band, but the one thing we do know is that it works! Most soccer regulations forbid the use of hair accessories. Some leagues say pre-wrap can be used only if it isn't tied in a knot - but most of us agree that tying a knot is the easiest way to go!
