According to Foot Vitals, the most common causes of foot cramps are fatigue and stress on the foot. Other likely causes of foot cramps are poor circulation, obesity, flat feet and diabetes.
While foot cramps can affect people of all ages, they are most common in athletes and older adults. Foot cramps can be a result of poor blood circulation, a side effect of a reduced activity level. Methods to prevent or improve foot cramps include exercising, eating a balanced diet, taking daily multivitamins and soaking the feet in warm water. If foot cramps are excessive, consultation from a podiatrist or foot doctor may be necessary.
