Ayla has brought an assortment of shoes to the laboratory to see which ones maximize her comfort and control of the pedals of a stickshift car. She begins by working each of the pedals barefoot, then in a pair of flat sandals with a single thin strap across the toes, then a pair of strappy high-heeled sandals, then some mid-heeled thong sandals, then some flat thong sandals, and finally, a pair of well-worn flip-flops. Which will she prefer? There's only one way to find out!
