I must be very lucky, this week ( 7/20 to 7/24)I went through security in TPA, MIA (twice) ORD, LAX and SFO and did not have to take my shoes off once ( though it was suggested in most places) and even more surprising did not once get the secondary either.
Reports here had said that at SFO they had been ordering everybody to take shoes off, but TSA guy only glanced at them and let me through.
I have two pairs of ECCOs I always use when I fly, could it be that they now can recognise them?? We can only hope.
