will running on a treadmill barefooted make it so my ipod will not shock me?

everytime I try and do this fitness stuff my wife is always saying we have to do in order that our insurance will be lower I get up there and start jogging and then almost fall off of the machine because my headphones will zapp me off and on and sometimes it's really sharp and destroys my rythm and then i have to do a whole set of stretches to get back to being preparred and by that time its time to leave and i haven't even gone half of a mile yet, somebody said i might keep gettting schocked because my shoes are condusctors and are attractive electiricty from the machine to my ipod and then against my headphones where they travel up to my body and burn me, they said if i run with no shoes on there would be nowhere for the electricity to go is this a solution or do i need to explain to the gym managemnt what's been happening to me so they can compensate something back to me and maybe get new of the machines?
