The arch of your foot is its main supportive structure. If this arch loses strength, the bony framework begins to collapse, causing your foot to flatten. Like a sagging bridge, the weakness in the middle strains the joints at both end of your foot.
Causes: There are many causes of flat feet. Some people are born with them. Others acquire flat feet as a result of arthritis, trauma, or musculoskeletal disorders.
Symptoms: Discomfort from flat feet often doesn’t appear for years. At some point, pain may be felt and walking may become awkward as increasing strain is put on your feet and calf muscles.
Related Problems: The excess strain from flat feet can cause other foot problems, such as hammertoes, bunions, heel spurs, arch strain, corns, neuromas, and sagging joints. Flat feet can also affect other parts of the body, causing fatigue, pain, or stiffness on the ankles, knees, hips and lower back.
