I Thought and do use it for a wrap round the knees & the padded knee bar.
i found it held my knee's nice and tight to the knee bar. If anyone knows any different then i would like to know as well.
In the little book that comes with them there is a bit somewhere that talks about wrapping somthing round the knees. I think it's at the tips bit, but I cant find my little book so im not exactly sure.
But i know that it helps me when put them on.
