These are made by & available through Orthoflex when I ordered my
saddles from them a few eyars ago. Call OF, or access them through
their link on the endurance page. I haven't tried them, so can't speak
to how well they do. I used my favorite old stirrups (original Trail
Techs) when I bought the saddle, so didn't order them.
