The heel is the largest and the most important bone among the 26 bones present in your foot. It supports your entire body weight while you walk and at the same time acts like an insulator to absorb the impact of hitting the ground while performing rigorous activities like running. An interesting fact - when you walk the stress impact on your foot is 1 ¼ times your body weight which increases to 2 ¾ when your run. Heel pain is a common problem that people face especially women. Mild heel pain can be short-term and may disappear on its own.
