Flexitol is a product used for reducing or minimising hard skin on heels, you apply it twice a day religiously and it works brilliantly I have used it many times on old ladies heels that were so badly split they couldn't walk, the hard skin completely disappear and returned it to normal soft skin again, I ain't no Dr but I don't see why it wouldn't do the same for you, it takes a few weeks to show the effect but worth a try, you can buy it readily in any Pharmacy.
