Baking Soda is a wonderful natural home remedy for soaking your feet in and the baking soda helps soothe your feet and makes it easier to remove any rough and dry skin from your feet with a pumice stone afterwards.
When my feet are becoming, dry, cracked etc then I mix some baking soda into a foot bath of warm water and soak my feet in the baking soda and water for an hour and then afterwards I use a pumice stone to remove the dry cracked skin parts of the feet.
It's also very soothing to soak your feet in baking soda and water and feels much better after a hard day when you spend all day on your feet. .
