The hallux pl. halluces, also known as the big toe or "thumb toe" is the innermost toe of the foot, counted as digit I.
In humans, the hallux is longer than the second or pointer toe for a majority of people. This is an inherited trait in humans, where the dominant gene causes the normal length hallux while the homozygous recessive geneotype presents with a longer second toe. (Commonly known as "mitten foot").
In birds with anisodactyl or heterodactyl feet, the hallux is opposed or directed backwards and allows for grasping and perching.
People with the rare genetic disease fibrodysplasia ossificans progressiva characteristically have short big toes.
The big toe is the most common focus of gout and Ingrown nail attacks.
