According to Foot Care For You, a longer second toe means that the first metatarsal bone is shorter than second metatarsal bone, or the first metatarsal bone is unstable. A longer second toe is associated in foot reading with strong leadership skills, Celtic origin or royal ancestry. According to the Museum of Hoaxes, these claims are unfounded.
According to Foot Care For You, a longer second toe is called Morton's Toe, named for the physician Dr. Dudley Morton. It's also called the Greek Foot. It's caused by abnormalities of the metatarsal bones, which are finger-like bones that attach to the toes. Normally the first and second metatarsal bones are the same length; however, in the case of Morton's Toe, the first metatarsal bone that is attached to the big toe is shorter than the second bone that's attached to the second toe, making the second toe longer. Morton's toe can also be the result of an unstable first metatarsal bone, which causes too much motion of the bone and thus makes it shorter. The condition is hereditary.
