Morton's toe (or Morton's foot, Greek foot, "Royal toe", "Turkey toe", "LaMay toe", "Sheppard's toe", Morton's syndrome, long toe, boss toe) is the condition of a shortened first metatarsal in relation to the second metatarsal. It is a type of brachymetatarsia.
The metatarsal bones behind the toes vary in relative length. For most feet, a smooth curve can be traced through the joints at the bases of the toes. But in Morton's foot, the line has to bend more sharply to go through the base of the big toe, as shown in the diagram.
This is because the first metatarsal, behind the big toe, is short compared to the second metatarsal, next to it. The longer second metatarsal puts the joint at the base of the second toe (the second metatarsal-phalangeal, or MTP, joint) farther forward.
If the big toe and the second toe are the same length (as measured from the MPT joint to the tip, including only the
The name derives from American orthopedic surgeon Dudley Joy Morton (1884–1960), who originally described it as part of Morton's triad (a.k.a. Morton's syndrome or Morton's foot syndrome): a congenital short first metatarsal bone, a hypermobile first metatarsal segment, and calluses under the second and third metatarsals.
Confusion has arisen from "Morton's foot" being used for a different condition, Morton's metatarsalgia, which affects the space between the bones and is named after Thomas George Morton (1835–1903.)
Morton's Toe is a common variant of foot shape. Its recorded prevalence varies in different populations, from a few percent to tens of percent.
The most common symptom experienced due to Morton's toe is callusing and /or discomfort of the ball of the foot at the base of the second toe. The first metatarsal head would normally bear the majority of a person's body weight during the propulsive phases of gait, but because the second metatarsal head is farthest forward, the force is transferred there. Pain may also be felt in the arch of the foot, at the ankleward end of the first and second metatarsals.
In shoe-wearing cultures, Morton's toe can be problematic. For instance, wearing shoes with a profile that does not accommodate a longer second toe may cause foot pain. A small (80-person) study found no statistically significant difference in the frequency of longer second toes between people with and without ingrown toenails, but tight and ill-fitting shoes are generally considered to increase the risk of ingrown toenails, and shoes are often too tight on the toes.
Morton's toe, especially the second-toe-is-longer versions, has a long association with disputed anthropological and ethnic interpretations. Morton called it Metatarsus atavicus, considering it an atavism recalling prehuman grasping toes. In statuary and shoe fitting, a more-protuberant second toe has been called the Greek foot (as opposed to the Egyptian foot, where the great toe is longer). It was an idealized form in Greek sculpture, and this persisted as an aesthetic standard through Roman and Renaissance periods and later (the Statue of Liberty has toes of this proportion). There are also associations found within Celtic groups. The French call it commonly pied grec (just as the Italians call it piede greco), but sometimes pied ancestral or pied de Néanderthal.
So no evolutionary benefit at all. However, while growing up my shoes did not allow for this and a result is the hammer deformity I have now on both feet.
