This callus remover works much better than pumice stones and other products that really just get to the first layer. For tougher calluses you really need something like this that will help get rid of that hard skin that have built up. I am find with getting calluses shaved off at the spa, but am too chicken to do that at home so this is a great product for in the shower between spa visits, especially if you're prone to calluses and want to maintain soft post-pedicure feet. Be sure and moisturize heavily after using to treat the new skin well.
