Jenny has brought another assortment of shoes to the laboratory to see which ones maximize her comfort and control of the pedals of a stick-shift car. She begins by working each of the pedals barefoot, then tries a pair of flat-heeled lace-up sandals, then a pair of flat thong sandals, then a pair of low wedge-heeled thong sandals, then a pair of mid-heeled strappy sandals, then a pair of high-heeled thong sandals, and finally, a pair of all-star-style sneakers. Which will she prefer? There's only one way to find out!
