Morton's Syndrome

Morton’s Syndrome happens when the bone in the big toe (1st metatarsal bone) is too short and does not provide proper stability for the foot. The second toe (2nd metatarsal) bone is then forced to handle the additional pressure. The arch and ankle often roll down and inward until the 1st metatarsal makes contact with the ground.


The most common symptoms associated with Morton’s syndrome include recurrent callousing and constant tenderness under the ball of the foot, also called metatarsalgia. You might also feel significant pain in the 2nd ball joint and mid-arch. Heel pain (plantar fasciitis), aching calves (shin splints), and ankle, knee, and hip pain may occur as joint alignment in these areas depends on the foot for stability.


Morton’s Syndrome is most often a congenital condition that exists in 18% to 28% of people. It can also be caused by a shortened 1st metatarsal after bunion surgery.


Custom orthotics and custom-fit footwear are both integral to the effective treatment of Morton’s Syndrome.
