Why do heels crack?
Cracked heels, or heel fissures, are splits in the skin around the heel. When pressure is put onto the heel from our bodyweight while walking and standing, the skin needs to stretch and spread out a little. If the heel cannot stretch because the skin is dry and inflexible, it will split.
How to prevent and treat cracked heels
For cracked heels try a keratin based treatment. The regular use of a file can also help you get smooth and soft heels.
