Bailey has brought in another assortment of shoes to try out on the laboratory's pumps. She begins by working the pedals barefoot as a control, then tries a flat jelly thong sandal, then a nearly-flat T-strap sandal, then two different styles of gladiator-like strappy sandals. She makes all of them bend as far as they can, and then draws her conclusions.
