Zonah is back with another group of shoes to test on our laboratory pump pedals. This time, she begins with a pair of strappy "gladiator" sandals, a pair of thin thong sandals, a pair of flip-flops, a pair of high-heel sandals, and a pair of almost knee-high shiny boots. All are in black or very dark colors, which contrast nicely with her pale skin and black toenails. While Zonah's lung power has yet to fail her, she will always be ready to use our pedal-operated air pumps when needed.
