A dorsal or posterior subluxation of the first metatarsal, often found bilaterally, is one of the most common, hidden, and often asymptomatic problems in the exercising individual. It most often creates or aggravates problems elsewhere. The origin is usually the result of wearing shoes that are too small, a fact seen frequently in over 50% of the athletic population.
Like weight, many people think that their shoe size should be as small as possible – the smaller the better. In addition, people often think that the dimensions their feet have attained by age 20, 25, or even 30 will remain the same throughout life. This is not true. In many individuals, the foot will change in size in later years regardless of their age.
