It depends a lot on the saddle, the pad and what kind of riding you do. I wouldn’t say they are all bad just like all treed saddles are not good.
Certainly, treeless saddles work very well for many endurance riders who are logging a lot of miles in them. So they can be very effective and it’s worth looking to see what those riders are using. Some treeless saddles have more internal structure, some have gullets and some of the pads are very good.
However, they are not a “one size fits all” deal and they are not all created equal. Many people don’t know how to evaluate the fit of a treeless saddle and some horses just don’t do well in them.
I mostly ride in a treed saddle (I’m not sure how a treeless saddle could do a really good job of dissipating a rider’s weight when landing from a jump) but I like the Freeform and use it when riding a horse that doesn’t work with any of my saddles or when I’m hacking (more comfy than bareback). I do use a skito pad under it.
I had the worst luck with the Heather Moffett Pheonix. That model has a gullet so you should not need to use a pad but it made my horse’s back sore pretty quickly. I’m not a big fan of the early Ansur saddles because there was no spinal clearance (I think the newer models do have them). I wasn’t a fan of the Barefoot because of the lack of twist and the set of the stirrup bars. I liked my Torsion on one horse, but not on the horse I have now.
That said, I’ve seen so many people riding in treed saddles that don’t fit! It drives me nuts to see horses with saddles with no clearance over their withers or where the saddle is perched on their backs like a party hat. The bottom line is you need to make an educated choice about the type of saddle that works for you and your horse.

Treeless saddles put your weight directly, unless you pad it excessively, directly on the spine and are a waste of good money, unless you like paying your vet. It is the reason why there are trees, they lay on the muscle layers along the spine. Work on the ground, put the horse on a diet, but if you are interested in saving your horses’ back, don’t ride in a treeless. It’s is a scam for susceptible people who do not understand anatomy very well.[/QUOTE]
