I bought a Missouri Fox Trotter mare, and my first ride on her in my old saddle (a very expensive big name saddle) she bucked me off because it didn’t fit her short curvy back. Fast forward many saddles, trainers and months later, I found and built my dream saddle, a Steele Mountaineer, custom built to fit my horse and I. The saddle stayed put and my horse was free moving and comfortable carrying me. The seat was so comfortable and I love the endurance stirrups, my knees didn’t hurt after the ride. Thank You!!
