This DIY cracked heel foot balm is my favorite way to heal dry cracked heels, and it makes an excellent overnight moisturizer for your feet. I notice a massive improvement in my heels in just one use. When you use this foot ointment regularly, your feet's skin, especially the heels, turns super soft and feels amazing. Say goodbye to cracked heels! Essentials Oils such as doTERRA Tea Tree help treat any underlying fungal infections.
