Webbed toes is the informal and common name for syndactyly affecting the feet—the fusion of two or more digits of the feet.

Syndactyly occurs when apoptosis or programmed cell death during gestation is absent or incomplete.

In contrast, when left untreated it is very uncommon for webbed toes to cause complications beyond cosmetic considerations.

The end results depend on the extent of the webbing and underlying bone structure.

In rare instances, nerve damage may lead to loss of feeling in the toes and a tingling sensation.
