Alina Long has brought in a few shoes to try out on the laboratory's pedals. She begins with a pair of pink flat-heeled thong sandals, then tries a pair of silver high-heeled t-strap sandals, a pair of tan and black high-heeled sandals, then a pair of red high-heeled pumps, and finally, a pair of black high-heeled, sling-back, peep-toe quasi-boots.
