I ride mild trails and play in the arena with a Barefoot Tahoe. I’m 180# and I often ride for a few hours at a time.
I have never felt insecure in this saddle nor been uncomfortable during a ride. More importantly, my horse has never shown any indication of discomfort or soreness. I ride with a quality pad that was designed specifically for use with the Barefoot saddles. You CANNOT skimp on pad quality with any treeless saddle or you will be sad you did.
What I love about the saddle is that it is incredibly lightweight and comfortable for me. It is easy to clean. I was able to outfit it with a breast collar for some added security and I bought pommel inserts so it has a better range of fitment for the horses I use it on, though I generally only use the soft insert. I am comfortable in this saddle with stirrups and without. The Newbuck leather feels grippy to me.
If I am hitting the mountains, going for an extended ride, or need to carry a lot of stuff with me, I will grab a western saddle, but for the day to day stuff, the Barefoot has been perfect for me.
I have used the barefoot on my fatty-mcfat-fat draft dross, my stocky QH, a full Belgian draft, and more recently, my WB type Trehekner/Perch cross with no shims or extra padding or problems.
I would recommend trying to find someone in your area with a treeless saddle (look for several brands) and see if you can borrow one to see what you think for yourself. There is a huge difference in quality between brands, you definitely get what you pay for, and they definitely feel different than a traditional treed saddle. Pay attention to reviews, and look into Facebook or Yahoo groups - that is where I got my info before I made the decision to buy. (My Barefoot was not cheap)
This is the one I have…
