Sedusa 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 barefoot, then moves on to a pair of flat-heeled T-strap sandals, a pair of simple wide-strap sandals, two different flat-heeled thong sandals, and two different wedge-heeled strappy sandals, and finally she takes a "victory lap" with her favorite. Which one was that? There's only one way to find out!
