I've suffered from cracked heels for all my adult life, previously no amount of creams etc would solve it. I used to go for pedicures, wherein my feet would be soaked in water for a length of time, and then depending on the place filed, scrubbed or even razored to remove hard skin. I assumed this was how you were supposed to solve this problem, short of seeing a podiatrist, and duly trotted off every few months to have one of these pedicures. Each time apologising for my dry feet.
This year, at the grand old age of 42 and thanks to an informative thread on here I finally discovered that in fact you should be filing your feet DRY. £6 glass foot file later, and my feet are sorted and better condition than at any point in my adult life.
Why are we forking out £60 in some areas for spa pedicures, which make the condition of your feet worse rather than better and in some cases cause actual damage to the skin.
I'm not debating that nicely polished and tended for toe nails are worth the money, and generally a third party professional seems to get a much better result than I can manage. So a file and polish is not a scam.
