This cheap product you’ve already got in your kitchen cupboard can help reduce cracked heels

Sleep

This is how you use the cornstarch: liberally powder your heels with the stuff before you go to sleep. Make sure the cracks are properly covered in cornstarch. Then, put on socks and go to bed. Rinse away the cornstarch in the morning and after a while, you’ll notice that your heels are starting to heal and they become smooth again. Are the cracks in your heels really deep? Then it might be handy to first file your feet with a special foot file. Afterwards, just use the cornstarch as instructed above and the trick will work wonders for you as well.
