Savannah 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 in a pair of cutaway high-heeled pumps, then moves on to a pair of medium-high wedge-heeled T-strap sandals, then a pair of flat thong sandals, then a pair of strappy flip-flops, then finally, she works the pedals barefoot. Which will she prefer? There's only one way to find out!
