Ok this is funny too - the first time I saw this - I didn't even SEE the sneaker! I thought it was someone singing with a head-worn microphone (I see that's her hair now) but it looked liked a head-worn concert mic with her body positioning and all - THEN I saw the sneaker! LOL...Our gym tells us if it flies off DONT TOUCH IT bc its a deduction....if it is accidently kicked or hit it is ok, bc it becomes "part of the floor" when it falls off, but that you cannot physically move it....now I am wondering if that is true...and if it is the same with bows....
