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!
