  1. Note: The p-values address the following null hypotheses. Footwear specific change: tests against a null hypothesis of no change between visits 1 and 2 for the target footwear only; Change differs by footwear: tests against a null hypothesis of similar change between visits 1 and 2 for any footwear; any change: tests against a null hypothesis of no change between visits 1 and 2.
