Toes are the digits of the foot of a tetrapod. Animal species such as cats that walk on their toes are described as being digitigrade. Humans, and other animals that walk on the soles of their feet, are described as being plantigrade; unguligrade animals are those that walk on hooves at the tips of their toes.

There are five toes present on each human foot. Each toe consists of three phalanx bones, the proximal, middle and distal, with the exception of the big toe (Latin: Hallux). The hallux only contains two phalanx bones, the proximal and distal. The phalanx bones of the toe join to the metatarsal bones of the foot at the interphalangeal joints. Outside the hallux bones is skin, and present on all five toes is a toenail.

The toes are, from medial to lateral:

The first toe, also known as the hallux ("big toe" or "great toe")the innermost toe, the "thumb toe".

The second toe, "long toe" or "pointer toe", "index toe"

The third toe, or "middle toe"

The fourth toe, or "ring toe"

The fifth toe, "baby toe", "little toe", "pinky toe", "small toe" or "tiny toe", the outermost toe

In humans, the hallux is usually longer than the second toe, but in some individuals, it may not be the longest toe. There is an inherited trait in humans, where the dominant gene causes a longer second toe ("Morton's toe" or "Greek foot") while the homozygous recessive genotype presents with the more common trait: a longer hallux.
