Anastasia has brought an assortment of shoes to the laboratory to see which ones maximize her comfort and control of the pedals of the laboratory pumps. She begins by working each of the pedals in a pair of T-strap sandals with a low wedge heel, then moves on to a pair of peep-toe pumps with a higher wedge heel, then a pair of flat flip-flops, then a pair of closed-toe ballet flats, then finally, some flat-heeled thong sandals. Which will she prefer? There's only one way to find out!
