Amergo Amerigo Aluminum Armor These are aluminum stirrups that are resistant to degradation and highly durable. They are lighter than stainless steel stirrups and heavier than plastic stirrups, offering a balance of lightness and stability. The holes for the stirrup leathers are angled downwards towards the horse's body, making it easier to keep the stirrups in the correct position. The step has a unique design with holes to allow dirt to naturally fall off the stirrups while riding.
