I saw all the online photos of people who had tried this and had skin literally peeling off their feet.  I soaked in the required time and waited a week for the peeling to begin.  Unfortunately, my skin just seemed extra dry but did not peel off.  After a few more days, I gave up and used a pedicure filing board to take off the dry skin.  My skin was super soft after, which was great, but did require a bit more effort than I expected.
