According to Dr. Donald Pelto for FootVitals, possible causes for foot soreness include a new pair of shoes, pregnancy, overuse, ligament strain, age, obesity, the use of improper or ill-fitting footwear, flat feet or a sports injury. More serious causes are tendinitis, arthritis, foot fracture, foot ulcer, bunions, sprained ankle, broken foot, plantar warts, gout, gangrene, Morton’s neuroma, diabetes, tarsal tunnel syndrome, bone tumor, ankle strain and Achilles tendinitis.

Pelto lists additional causes for foot pain as metatarsalgia, foot deformity, nerve entrapment, spurs, athlete's foot, Kohler disease, calluses, pes planus, pes cavus, overpronation, hallux rigidus, turf toe and hallux limitus. He advises that a person experiencing chronic foot soreness see a doctor or local podiatrist to evaluate the symptoms and assess a course of treatment if necessary. The foot contains 26 bones, 33 joints and more than 100 muscles, ligaments and tendons. It is very common to have foot pain.

A doctor evaluates several pieces of information to diagnose the cause of a person's foot pain, including his lifestyle and daily activities. Additional testing may be necessary, such as X-rays, ultrasounds, blood tests, magnetic resonance imaging, computerized tomography scans, electromyograms, synovial joint fluid aspiration and nerve conduction velocity studies, notes Pelto.
