What is referred here as "Celtic toe" is normally called Morton's toe.

http://en.wikipedia.org/wiki/Morton's_toe
..Although commonly described as a disorder, it is sufficiently common to be considered a normal variant of foot shape (its prevalence varies with different populations, but around 10% of feet worldwide have this form). In shoe-wearing cultures it can be problematic: for instance, in causing nail problems from wearing shoes with a profile that doesn't accommodate the longer second toe.

It has a long association with disputed anthropological and ethnic interpretations. Morton called it Metatarsus atavicus, considering it an atavism recalling prehuman grasping toes. In statuary and shoe fitting it has been called the Greek foot (as opposed to the Egyptian foot, where the great toe is longer). It was an idealised form in Greek sculpture, and this persisted as an aesthetic standard through Roman and Renaissance periods and later (the Statue of Liberty has toes of this proportion). The French call it pied ancestral or pied de Néanderthal, believing it to be a sign of intelligence. Podiatrist/archaeologist Phyllis Jackson has interpreted it as a characteristically Celtic toe, as opposed to a Saxon toe. Cleopatra was known to have this, and many consider this trait to be a sign of beauty.


I will also add that many Egyptian idols such as the lion-headed Sekhmet had Morton's toe so despite the widespread depiction of the Egyptian form in sculpture by the Egyptians it did too find their way into some sculpture as, obviously, some idealization of beauty.



Despite redish light coloured hair and fair skin, Morton's toe and very long and narrow a foot I would very strongly doubt that I have Celtic forebears.

(P.S.: In Germany as the UK the most common widths today are wide. The "Greek foot form" is a tiny minority.)
