The LeMieux Vector Control Stirrups offer technical advances for safety with style and top performance. Vector Control Stirrups are lightweight aluminum yet very strong and stable. They feature an integrated safety branch with a two-stage release system that ensures it opens only when you need it to. In the event of a fall, pressure against the outer branch of the stirrup causes it to release. This action does not occur during regular riding, turning, jumping or landing. In good condition.
