The hallux, the big toe or great toe is the innermost toe of the foot.
It may not be the longest toe on the foot of some individuals.
Counted as digit I (one).
Usually longer than the second toe.
This is an inherited trait in humans, and the dominant gene causes a longer second toe, while the homozygous recessive genotype presents with a longer hallux.
A common problem involving the big toe is the formation of bunions (hallux valgus), a deformity characterized by lateral deviation of the great toe.
The most common locus of ingrown nails and gout attacks.
