Ginger 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 pointy high-heeled pumps, then a pair of very bare high-heeled sandals, then a pair of medium wedge-heeled thong sandals, a pair of flat toe-loop sandals, a pair of shiny knee-high stiletto-heeled boots, a pair of flat thong sandals, and a pair of flat T-strap sandals. Which will she prefer? There's only one way to find out!
