It may take several weeks of gently daily cleansing to work your way through the built-up hardness of the sole of the foot. Use the pumice stone at the end of your bath, when skin is softest, and rub the rough spots gently. Some people try to scrape all the old skin off the first time they use the stone, which can actually cause injury to the foot and invite soreness or even fungus. Take your time, use a moisturizing soap, and work with the pumice stone for several weeks before expecting results.

If you've already tried a pumice stone and your feet are still rough, you may want to look at the way you're treating those tootsies. Are you parading barefoot on hot sidewalks? Wearing bad shoes? Spending lots of time on a sandy beach? We forget that our feet are made from skin just like the rest of our bodies, but they get much harder wear. If your shoes are causing calluses, if you're not properly moisturizing your feet, or if you have contracted athlete's foot or nail fungus, you may continue having roughness until the underlying problem is solved.
