Amiee has brought an assortment of shoes to the laboratory to see which ones maximize her comfort and control of the pedals of the laboratory pumps. She begins by working each of the pedals barefoot, then moves on to a pair of closed-toe flats, then a pair of high-heeled pumps, then two different pair of flat thong sandals, and finally, a pair of strappy slide-on sandals that are much too cute to call "flip flops." Which will she prefer? There's only one way to find out!
