Lorenzo, me thinks you have that reversed.
It's the woman's seed that crushes the head while the serpent's seed goes after the heels. The woman is not Satan, nor an analogy of him.
He's talking to "the serpent" in verse 14, 15, (ie "thy & thou").
Genesis 3:13-15 KJVS
And the Lord God said unto the woman, What is this that thou hast done? And the woman said, The serpent beguiled me, and I did eat.
[14] And the Lord God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life: [15] And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
