I am interested in the barefoot saddles. They look very comfortable for the rider, but I have heard that without a tree the rider's weight is not distributed so the horse develops sore spots where the bulk of the weight would be, especially if you have a not-so-good rider who bounces more or is unbalanced. But it seems like people like them. I like the idea that it would fit a lot of horses, and my hard-to-fit mare, but I am hesitant to go treeless. My Aussie fits about the best of anything I tried, but I still think it is too tight on her withers. I can get a hand in there when it's cinched, but it's a squeeze. All other western saddles I tried did the bridging thing, and/or were tight in the withers. Anyway, I would be interested in trying out the barefoot at some point (it's kind of pricey but worth it if it works and would fit my next horse) but am worried about the pressure on the spine and so on. Any opinions on that specifically? I just trail ride. I did try a Tucker on my mare at one time that seemed to fit well also, but it was also higher priced.
