The Seba library treats Achilles Heel in 8 passages, across 4 authors (including Jung, Carl Gustav, Hillman, James, Rank, Otto).
It is the Achilles heel of even the most heroic consciousness: somewhere the strong man is weak, the clever man foolish, the good man bad, and the reverse is also true.
Jung identifies the inferior function as the structural Achilles heel of consciousness, the invariably vulnerable pole that undermines the most powerful psychic organization.

Achilles's heel, Oedipus (swellfoot), Hercules (the crab at Lerna), Alexander the Great (wounded in the ankle), Odysseus's leg, Jason's single sandal, Philoctetes, Bellerophon who limps—all these are marked in the foot.
Hillman argues that the wound to the lower extremity is the defining signature of puer psychology, with Achilles's heel as the paradigmatic instance of the spirit's failure to fully ground itself in material existence.
, Senex & Puer, 2015thesis
the feet, which come out last of all, are mostly the weak part. The swollen feet of Oedipus, besides Achilles' heel, show that it is a question of that part of the body which actually on leaving last touched the mother's genitals.
Rank interprets the Achilles heel as the somatic trace of birth trauma, the anatomical site of the hero's final attachment to the maternal body and hence the ineradicable mark of mortal vulnerability.
, The Trauma of Birth, 1924thesis
We know from the famous story of Achilles that the heel is a particularly sensitive spot; it has thus become the proverbial weak spot of the hero. First, the heel is on one's back side; it therefore signifies a place where one doesn't see oneself very well where one is unconscious of oneself.
Von Franz reads the heel as a topographic symbol for the unconscious blind spot — the place on the hero that remains unguarded precisely because it cannot be seen, making it the natural entry point for destructive forces.
, Archetypal Patterns in Fairy Tales, 1997thesis
You know of the Achilles heel, the only place where Achilles could be wounded. Many other savior gods were often wounded in the feet... One must be wounded to become a healer.
Von Franz situates the Achilles heel within a universal mythological pattern in which the savior or healer must first sustain a wound — the vulnerable point is not merely a weakness but the precondition for healing power.

The snake bites the little prince on the heel, which is obviously where a snake would bite. This is also a mythological motif. You know of the Achilles heel, the only place where Achilles could be wounded.
Von Franz connects the serpent's bite on the heel in the Little Prince narrative to the Achilles heel motif, identifying it as the archetypal point of fatal vulnerability shared across savior mythologies.

Having given her mortal husband, Peleus, a son, Achilles, she wanted to make him immortal and hardened him every night in the fire or in hot water, but the heel by which she held him remained vulnerable and it was there that he was mortally wounded.
Von Franz recounts the mythological background of the Achilles heel in the context of the mother archetype's ambivalence — the very act of protection creates the fatal weakness, binding heroic invulnerability to maternal attachment.

The pains in the heel did not disappear. They do not belong in the picture we have just sketched, for the heart is in no way connected with the heel, nor does one express sorrow through the heel.
Jung presents a clinical case in which unexplained heel pain resists interpretation through emotional repression alone, prompting recourse to dream analysis and implicitly invoking the mythological resonance of the heel as a locus of deeper psychic disturbance.
