Alternate — inverted (reversed-direction) heel hook
Inverted Heel Hook is the alternate name for the inside heel hook — using “inverted” to flag the reversed-direction rotation relative to the outside heel hook.
Etymology. “Inverted” specifies the directional inversion (inward rather than outward); “Heel Hook” attaches the submission category. The label is commonly confused with the outside heel hook’s “reverse” naming.
Mechanics. The inverted (inward) heel rotation loads the knee against the direction it has minimal tolerance for — the lock can finish from positions where the defender has barely felt the threat.
Cross-reference. “Inside Hook,” “Inner Heel Hook,” and “Reverse Heel Hook” are alternate names. Full mechanical coverage on Inside Heel Hook.
