Zonah 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 with her exceptionally flexible bare toes, then moves on to a pair of high-wedge-heeled peep-toe sandals, then some high-heeled pumps, then some (rare) high-heeled thong sandals, then some low-heeled T-strap sandals, then two different styles of flat-heeled thong sandals. Which will she prefer? There's only one way to find out!
