Do you have a toe that’s started to cross over or under its neighbor? If so, you have far more than just a cosmetic problem on your hands. Overlapping and underlapping toes are more common than you might think. The most frequent situation is a pinky toe that crosses over or under the fourth toe.

Morton's neuroma is a painful condition that affects the ball of your foot, most commonly the area between your third and fourth toes. Morton's neuroma may feel as if you are standing on a pebble in your shoe or on a fold in your sock.

Most commonly, the pinky toe overlaps or underlaps the fourth toe. Family members often spot the congenital deformity of an overlapping toe early in an infant’s life.

A Morton's neuroma usually causes burning pain, numbness or tingling at the base of the third, fourth or second toes. Pain also can spread from the ball of the foot out to the tips of the toes. In some cases, there also is the sensation of a lump, a fold of sock or a "hot pebble" between the toes.
