Dry feet with cracked heels can be treated by the following methods: first, do not wear too exposed shoes in general, because too dry feet can lead to cracked heels. Second, you can properly consume more vitamin and fiber-rich foods, such as fruits and green vegetables, because when the body lacks vitamins can also lead to dry and cracked heels. Third, you need to take in meat, such as leaner beef and lamb, fish and shrimp, because these meats contain fat-soluble vitamins, which will participate in skin keratinization and prevent local cracking. Fourth, you can locally apply some oily substances, such as erythromycin ointment, and petroleum jelly, etc. to protect the local wounds so that they heal as soon as possible. Fifth, if the local fissures are large, you need to go to the hospital to see a surgeon or a dermatologist for treatment.
