The Stephi Light stirrups are made of nylon. The stainless steel insert guarantees maximum grip and hold and the inclined, very robust step surface facilitates the cushioning function of the ankle. The front of the insert is smooth so as not to scratch the saddle. The asymmetrical design of the upper part favors the correct position of the stapes. Each pair of stirrups is subjected to a breaking load test. They are heat and cold resistant.
