Amerigo Stirrup Irons are made from aluminum and the special design of the surface holes creates a self-cleaning tread, as well as excellent grip for all types of boots. Furthermore, the 30 degree inclination of the hole through which the stirrup leathers are threaded allows the stirrups themselves to be constantly in the correct position therefore enhancing the grip further on the riders boots. The new Amerigo stirrup iron combines hi-tech qualities and comfort, in keeping with Amerigo’s philosophy aimed at innovation and attention to detail for both horse and rider.
