At Dolly's insistence, Nora has brought a selection of shoes into the laboratory, to see which ones work best for pedal pumping. Barefoot pumping is not allowed due to safety regulations, but that's what most of the ladies would do if allowed. So the hunt is on for the most barefoot-like shoes, and a number of styles are tries, ranging from the obvious flat sandals to heels to closed-toe flats. We can see what Dolly prefers to wear, but which one will Nora pick?
