Bellah 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 in a pair of flat thong sandals, then a pair of flat sandals with a thin single lateral strap, then a pair of mid-heeled thong sandals, then a pair of mid-heeled strappy sandals, then a pair of medium-high wedge-heeled thong sandals, then a pair of strappy lace-up flat sandals. Which will she prefer? There's only one way to find out!
