Correct. You shouldnt really put stirrups on a saddle that doesnt have a tree. (Though I did ride like that once on someone else's horse) If you buy a bareback pad, cant you ride without stirrups? Or even just ride bareback with no pad.
Riding bareback your legs should hang forwards in the hollows behind the horse's shoulders.
I had bareback lessons - wearing a bp - to improve my balance. RI pointed out that both my seat and the mare were well fleshed and we didnt use a bad. You dont want to ride like that on a skinny TB.
You absolutely can put stirrups on a saddle that doesn't have a tree, and they can be used over literally 100 mile rides. Treeless saddles have been around a long time, they've got better and better, and they can overlap a little with a bareback pad depending on design.
A numnah with stirrup loops on a surcingle should be avoided, plenty of better, but more expensive, options. If you use stirrups on any bareback pad you should stick mostly to walk, perhaps sitting trot and should be riding without much weight in the stirrups at all.
As always, not that I saw the full question, the answer is "it depends".
Thanks -bareback isn’t ann option for me ant the moment unfortunately , and to sbloom for your valued expertise. I wrote the post, did a bit of research and then deleted post as the research seemed to suggest, as I suspected, that there would be unwanted pressure on the spine from where the leathers are attached to the saddle pad. Although it makes good sense that walk and sitting trot should be ok with minimum weight in stirrups ( thanks SB)
I’m going to have to be very patient I think and wait the time it takes for fitter to come out to my existing saddle which she will hopefully be able to fit successfully .
A second hand treeless saddle from a good make could be a safe interim option. There are always some on ebay, cheaper
than the sheepskin bareback pads. If you go down that route try and buy one with the special treeless pad included or source a second hand one as well. Torsion and Barefoot are reliable makes and fit most things with some shimming of the treeless pad. The hip saver from Barefoot is a game changer to give either a comfortable twist.
