Dry, rough, thick skin on your feet is very common because it can be caused by so many different factors. Standing for long periods of time, wearing poor fitting shoes or open back sandals, diabetes, thyroid disease and other health conditions, vitamin deficiencies, aging, obesity and even genetics can cause cracked heels and other skin problems. In addition to beginning healthier lifestyle habits, exfoliating is an excellent way to start improving the appearance and overall health of your skin. ZenToes makes this easy with our double sided pumice stones that can be used at home or while traveling. Simply soak your feet, hands or elbows in warm water until soft or use your pumice stone immediately after a warm bath or shower. Wet the stone with warm, soapy water and use the coarse side to buff away thick, dead skin and the finer side to smooth your newly exfoliated skin. You can also use the fine side for more sensitive skin on your body.
