Once again ...the summer is here and I am in my sandals everyday. I never have this problem at all over the winter because im in trainers most of the time. The backs of my heels are split, very deep cracks and bleeding too. I use a foot stone and smooth my heels more a less everyday and try to use foot balm to soften my skin but nothing seems to work. I cannot wear anything other than sandals, I really hate shoes and NEVER wear sock (yuuuuck) I dont wear anything on my feet in the house. What can i do to try and reduce some of the cracks and pain?
