was thinking about this today... why are they neccesary, was watching a couple of UFC fights today (i dont make a habit of this i promise !!! )

but one thing i noticed is i dont think i have ever seen a fighter slip on an adverstising in the octagon which is something that does seem to happen farily reguarly in boxing, maybe barefeet can grip the canvas a little better than the soles of a shoe or boxing boot?
