what is the big deal
OK here we go with the shoes thing again, why are you all crying so much about the shoes. Just take them off if the screener says to. Don't throw a fit. It takes less time to take them off and put them back on than it does to argue. Obviously those that do not want to take their shoes off and cause a scene at the airport have some sort of self esteem problem and have to draw attention to themselves. For these people, the button idea mentioned in a previous posting sounds pretty good.
I have traveled on 16 different flights in the last two months and at every checkpoint most people take their shoes off, those that do not and are asked to then make some sort of snide comment and do not take them off go through secondary screening, it is SOP and should be. OK I guess you want to know what airports these were ok here you go, SDF, LGA, JFK, ORD, SMF, DFW, SAT, IND... and just in case you want the rest of the airport I have traveled to in the past that this was the case here you go.
