Keilani has brought another 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 wide flat Birkenstock-style sandals, then in a pair of unusual high-heel thong/toe-loop sandals, then a pair of flat T-strap sandals, and finally, a pair of high-heeled dress sandals. Which will she prefer? There's only one way to find out!
