I wore a pair of sandals to garden approx. 2-3 weeks ago. My foot kept coming out of them and my foot was half on and half off the sandal. By the end of the day, the middle bottom part of my heels were so sore. I thought after a couple of days it would go away but they are both so sore and I don't know if I've done some permanent damage or what I should do. Any explanations? Should I go to a spesensoredt?
