Vivian has brought some additional shoes, both new and old favorites, to try out on the pedals at the laboratory. She starts out in a pair of black high-heeled sandals that continue almost to her knees. She then tries a pair of black medium to high-heeled sandal/mules, followed by a pair of white medium-heeled strappy sandals. These are followed by a pair of tan low-heeled thong sandals, and a pair of black, nearly flat-heeled thong sandals.
