Yes, a foot soak can help with dry and cracked heels. Soaking your feet in warm water helps to soften the skin and makes it easier to remove the dead and dry skin. Adding some moisturizing oils like coconut oil or olive oil to the foot soak can further nourish and hydrate the dry skin on your heels. It is important to follow the foot soak with exfoliation and moisturization to achieve the best results for healing and preventing dry and cracked heels.
