Ambriel 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 T-strap sandals, then a pair of mid-heeled thong sandals, then a pair of low wedge-heeled gladiator sandals, then a pair of mid-heeled toe-loop sandals, and finally, barefoot. Which will she prefer? There's only one way to find out!
