The Opera stirrup creates a more comfortable and secure ride ultimately causing riders to be more correct through the leg. This is due to the new patented loop construction concept from Acavallo which allows both arms of the stirrup to work independently and encourages the the stirrup to adhere to the saddle flap limiting friction between the leg and the stirrup. Stiffness and tension in the hips, knees, ankles and calves if eliminated through the larger stainless steel stirrup pad also providing ultimate grip.
