Overview
The straight ankle lock or "botinha" is one of the most fundamental leg submissions in grappling. Applied from a variety of entanglements, it targets the ankle and Achilles tendon through controlled extension of the foot. When executed with proper hip engagement and tight bite placement, it creates rapid pressure on the ligaments of the ankle joint, making it one of the most reliable and accessible leg submissions in both gi and no-gi competition.
In modern no-gi, the straight ankle lock is a core part of the lower-body attacking system, used both as a finishing technique and as a structural threat to force reactions. Athletes employ grips such as the figure-four, the gable grip, and reinforced wrist grips while using ashi garami variations to isolate the leg. Its balance of control, safety, and effectiveness has made it one of the most frequently attempted submissions at all levels of grappling.
