Here is a link to a Stubben saddle fitting FB page I follow. I find sometimes it’s correct and sometimes wildly or subtly off about things so want to double check.
Claim here is that newer dressage saddles are using longer stirrup bars set further back on the tree to encourage a “modern” dressage seat of standing in the stirrups and getting a longer looking leg. Is this actually a thing? Obviously rider and horse conformation dictate a lot about how the leg looks. Hard to drape on a horse with a really big barrel!!
