Your feet are so bloated all your shoes feel like vices. Even your new sneakers gave you blisters after half a day of waddling around in them. Save your feet and pick up a couple of 2-inch, glue-backed Velcro strips. Stick the soft side inside the heels of your shoes to prevent rubbing. Your poor feet have suffered enough lugging around the extra poundage; no need to add painful blisters to the mix.
