This is the second half of that long Wal-Mart line. By this time, her flats were really bothering her feet and my wife continued dipping her flats like crazy. At one point, she puts one foot up on the cart to air it out. She also stretches her leg several times by taking her shoe off and lifting her foot up behind her leg giving some impressive up close sole views. It's amazing what good things can come out of uncomfortable shoes!
