Outside Heel Hook

What This Is

The outside heel hook is the primary finishing submission from ashi garami and outside ashi garami. It loads the medial structures of the knee — the MCL and the posterior capsule — through external rotation. The foot is the handle; the knee is the target.

It is the most common heel hook in no-gi competition. It appears in the majority of leg entanglement finishes across ADCC and submission-only events. Understanding the outside heel hook is understanding the primary threat of the ashi garami position system.

The submission is illegal in IBJJF No-Gi at all levels. In gym training, it requires established mat culture, experienced training partners, and a clear understanding of the tap signal — which occurs before pain in functional heel hook training.

Safety First

The Invariable in Action

The outside heel hook requires the attacker to pull the heel away from their own body and toward the mat. Pulling the heel toward the body or upward changes the rotational axis and fails to load the medial knee. Many failed outside heel hooks apply force in the wrong direction — the defender feels it but is not in danger.

The heel hook grip is on the foot but the force is delivered to the knee. The attacker should feel resistance at the knee, not movement at the foot. If the foot is moving significantly, the angle is incorrect or the position is not fully established.

The outside heel hook is available because the ashi garami leg arrangement exposes the heel on the outside. No amount of grip adjustment creates this access — only the correct positional configuration does. If ashi garami is not fully established, the outside heel hook is not available.

The opponent’s primary defence is moving their hip. If they can extract their hip from against the attacker’s thigh, the isolation fails and the heel hook loses its mechanical basis. Maintaining hip loading through the ashi garami position is the prerequisite for the submission.

Defence and Escape

The outside heel hook has specific defences. Most of them must be applied before the rotation begins — not after.

• Hide the heel: Point the toes toward the opposite knee. This closes the access to the outside heel and forces the attacker to transition to a different attack. This is the primary and fastest defence.
• Secondary leg push: Use the free leg to push off the attacker’s hip immediately on entanglement recognition. Create distance before the grip is established.
• Belly-down escape: Turn toward the entangled leg — this is the correct rotation direction for outside ashi defence. Rolling away from the entangled leg completes the rotation and accelerates injury. Turn toward it to reduce the angle and create an escape path.
• Address the heel grip before rotation begins: Once the attacker begins applying rotational force, the defensive window is very short. The grip on the heel must be addressed before torsion is added.

Setup and Entry

The outside heel hook is the primary finish from several leg entanglement positions.

From Ashi Garami

The standard setup. Inside space established, hip loaded against thigh. The attacker grips the outside heel, pulls toward the mat and away from their body, and drives through with hip extension. The outside heel hook finish from ashi is the most common leg lock finish in the sport. See: Ashi Garami.

From Outside Ashi Garami

The outside ashi position exposes the outside heel with a different angle. The attacker is on the outside of the defender’s leg, which changes the rotation direction slightly but the target structures are the same. See: Outside Ashi Garami.

From 50/50

Both practitioners have mutual entanglement. The outside heel hook is available to both. Hip position and timing determine who finishes. See: 50/50.

From Backside 50/50

The backside configuration exposes the heel with less defensive access for the opponent. A premium position for the outside heel hook. See: Backside 50/50.

From K-Guard and Shin-Shin

Early entanglement positions that can transition to ashi and produce outside heel hook access. Used in standing leg entanglement entries.

Position Requirements

• Ashi Garami — Primary platform. Standard outside heel hook configuration. Highest reliability.
• Outside Ashi Garami — Outside line access. Heel exposed with different angle. High reliability.
• 50/50 — Mutual access. Race condition. Requires timing and hip control superiority.
• Backside 50/50 — Premium outside heel hook position. Reduced defender access. High reliability.
• Single Leg X (SLX) Bottom — Available in transition. Hip must be loaded during the positional change.
• K-Guard / Shin-Shin — Entry-level access. Transitional — leads to ashi before finishing.
