Amanda Bryant is preparing to inflate some test articles that will require use of the foot pumps, and so wishes she could just do it barefoot, so her toes could flex and scrunch as much as necessary. But she's been advised that she needs at least some sort of sole between her foot and the pedal, for safety and comfort over the long term. While skeptical, she brings in a few sandals, each with a different heel height and style, to see which is most like being barefoot.
