Definition - What does Leg Irons mean?
Leg irons are fetters or leg cuffs that are designed to restrict a person's leg movements, as well as make them feel vulnerable. They are usually made of steel or metal alloy, with chains that bind the ankles closer together. Some versions of leg irons include chains and belts that are designed to bind both the ankles and wrists.
Kinkly explains Leg Irons
In BDSM sex play, leg irons are used to impose dominance. The submissive partner is incapacitated by limited movement. A dom can choose to intensify the sub's vulnerability through verbal commands, shaming, whips, and other strategies. The key, of course, is to act within agreed boundaries. In fulfilling a dom-sub scene, respect should be involved. Personal esteem and safety remain at the core to the act.
