It's best to evaluate saddle fit initially without a pad. Don't work them like that, but just put it on and tighten the girth just to contact, then evaluate the angle the saddle sits at, space above the withers, "channel", etc.
Then put a blanket or THIN pad on under and lunge or do ground work enough to get them sweaty under the saddle and look for dry spots that indicate pressure points.
(Only mentioning that as a reason why the question was probably asked).
