The AVANTI Steel PLR horseshoes are designed to the fit the foot in a balanced fashion around the widest part of the foot (which is essentially the center of rotation of the coffin joint). In addition to balancing the shoe around the coffin bone, the AVANTI shoe incorporates an optimized leverage reduction design that will help reduce excessive strain and forces on many of the tendon, ligament, and soft tissue structures in & around the coffin joint. Modeled after the very popular Aluminum PLR Shoes, the AVANTI brings many of those same performance and treatment benefits in a durable steel version. Size #3 - W=5.50" x L=5.69"
