Picture of Foot Anatomy Detail

The feet sit at the end of the legs, and we use them for standing and walking. Feet are incredibly complex, comprised of 28 bones, 30 joints, and more than 100 ligaments. Small alterations in the foot can affect its whole structure and cause pain when walking.
Shoes can contribute to pain and problems with the feet. High heels can stress the feet, knees, hips, and back. Shoes that are too narrow can contribute to the development of bunions or swelling in the big-toe joint. Shoes that crowd the smaller toes may lead to the development of clawing or hammertoes and calluses and corns on areas that rub up against the inside of the shoes. Always choose comfortable, well-fitting shoes to protect your feet.
Some people get cosmetic surgery on their feet so they can wear fashionable shoes. These surgeries can do more harm than good. The American Orthopaedic Foot & Ankle Society has an official position statement advising against this type of surgery.
