Cassandra has brought an 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 in a pair of flat gladiator sandals, then a pair of kitten-heeled toe-loop dress sandals, then a pair of flat-heeled thong sandals, then a pair of sneakers, then a pair of flip-flops, then a pair of mid-heeled dress thong sandals, and finally, barefoot. Which will she prefer? There's only one way to find out!
