{"slug":"straight-ankle-lock","name":"Straight Ankle Lock","aliases":["straight foot lock","botinha","achilles lock"],"category":"submission","format":"both","level":"intermediate","summary":"A linear foot and ankle submission commonly attacked from straight ashi and related one-leg entanglements.","overview":["The straight ankle lock controls the opponent's leg while the attacker wraps the lower forearm around the ankle line. Unlike rotational heel hooks, its primary finishing direction is generally described as linear extension through the foot and ankle.","High-level foot-lock systems depend on leg control, hip position, and preventing the opponent from clearing their knee. The same entanglement also creates sweeps and stand-ups, so the position remains useful when the finish is defended."],"keyPrinciples":["Control the opponent's knee line before focusing on the foot.","Keep the wrapping arm connected high on the ankle line.","Use the legs to limit rotation and standing escapes.","Apply pressure slowly; foot and ankle injuries can occur before pain feels dramatic."],"entries":[{"label":"Single-leg X","description":"Maintain straight-ashi control after off-balancing the opponent."},{"label":"Open guard","description":"Collect a foot while connecting both knees around the captured leg."},{"label":"50/50","description":"Control the near foot while protecting your own knee line."}],"continuations":[{"label":"Sweep","description":"Use the leg entanglement to put the opponent on the mat and come on top."},{"label":"Technical stand-up","description":"Keep the captured leg and rise when the opponent retracts the foot."},{"label":"X guard","description":"Move underneath the hips if the opponent stands and frees the foot."}],"defenses":[{"label":"Free the knee line","description":"Move the knee beyond the attacker's legs before rotating away."},{"label":"Clear the wrapping arm","description":"Hand fight the forearm and recover the heel toward the mat."},{"label":"Control the secondary leg","description":"Prevent the attacker from maintaining hip connection while you disengage."}],"relatedTechniqueSlugs":["single-leg-x","fifty-fifty","inside-heel-hook","kneebar"],"athleteSlugs":["mateusz-szczecinski","mikey-musumeci","diego-pato","elisabeth-clay"],"rulesetNote":"Leg-lock legality changes substantially by age, belt, division, and ruleset.
