The Inflation Laboratory - Terra Evaluates Shoes for Pedal Pumping

Terra has brought in an assortment of shoes to see which ones work best for her on the various pedals at the lab. She starts out in a pair of high-heeled pumps, then tries a pair of white strappy low-heeled sandals, then a pair of shiny black low-heeled thong sandals, then a pair of black closed-toe flats, then a pair of silver high-heeled toe loop sandals, then a pair of dark brown high=heeled wedge sandals, and finally, she tries the pumps barefoot!
