Comprised of 26 bones held together by a structure of muscles, tendons and ligaments, the human foot is designed to support half of your body weight. It works as both a support and balance structure, providing motion for the rest of the body.
How important are healthy feet? While walking under normal conditions, your feet absorb 1 to 1.5 times your own body weight. When running, your feet absorb up to 3 times this amount. Combining this impact with any imbalance of your foot can cause injury or long-term damage.
Pronation is the normal action of the foot rolling from the outside of the heel to the inside, transferring your weight in a ‘heel to push-off’ manner. When the physical layout of your foot varies, pronation can be affected.
