What size should I choose on the saddle base?
Yes, you measure from the back top of the scapula to the back of the rear rib. that long can your Freeformssaddle be! What to keep in mind is that because the Freeformsaddle is soft and easy, it does not prevent the movements of the scapula blade even if you place it further on the scapula or get too much pressure if it is left behind the rear rib. Do not think how long a boom saddle may be because it's not the same because the pressure at the edge of the edges is not as big in a treeless saddle as in a boom. In this case you should choose as long a saddle as possible to distribute the pressure over a larger area of the pressure-reducing phenomenon found in the base of all Freeform Saddles

On this horse I would recommend the XSD 46cm long saddle.
