Nikki begins her test by working each of four different types of pedals barefoot, pushing them all the way down with her un-encumbered toes. Then she proceeds to try out a number of different types of shoes, to see which one provides the best freedom of movement. She starts with a red T-strap sandal with a low wedge heel, then tries a high-heel sandal, a flat thong sandal, a high-heeled pump, and finally, a rare high-heeled thong sandal. Which one do you think will be her favorite?
