I purchased these six years ago when I bought a jumping saddle. At the time, there were no places in Japan selling Lorenzini, so I imported them privately from Poland. I believe the regular price was over 40,000 yen. The paint is peeling in some places, but I think there are no problems with using them. They have a slight angle, making it difficult for your foot to slip out, and I think they are easy to use for beginners. No claims and no returns accepted. LORENZINI was the first company in the world to introduce biocompatible titanium, also used in the aerospace and medical fields, to equestrian equipment, and has obtained a patent. Lorenzini stirrups are lightweight and durable, using titanium and aluminum, and are designed based on ergonomics, providing excellent safety and stability. The step with excellent grip keeps the foot in a balanced and natural position. Size: Inner dimensions 12.2cm, step depth: 5cm, weight: 530g
