Also reccomend that clients with severely cracked heels either come in more often (once a month) for their pedicures, or do something at home to like using a pumice block, and applying cucumber heel therapy (which is awesome, I use it myself!!). I hate it when clients only come in a few times a year, and don't do anything to their feet at home. Then they just expect you to work a miracle and get it all off at once! Save your arms! There really needs to be a dual effort to keep those bad feet in shape. Clients have to do their part too. Especially people who run!! They should know that coming in every now and then isn't going to be enough to keep those calluses in check. That's my two cents on the matter. Later!
