* Pigeon's Feet: Pigeons have feet that turn inwards, with their toes pointing towards each other. This is due to their anatomical structure, designed for perching and walking on narrow surfaces.
* Human Feet: When a person's feet turn inwards, their toes point towards each other, resembling the way a pigeon's feet are positioned. This inward turning of the feet is called "in-toeing" or "metatarsus adductus".
* Descriptive Term: "Pigeon-toed" is a direct comparison of the way human feet appear to a pigeon's feet. This descriptive term has been in use for centuries.
Therefore, the expression "pigeon-toed" is a straightforward, descriptive comparison that accurately reflects the physical appearance of the condition.
