the idea for reducing perineal pressure is to be supported on the sitbones.
if the saddle doesn't cradle the sitbones well, then something else has to hold you up...
first try to determine what minimum saddle width will generally support the bones without allowing you to slip off, side to side. Not all 143 saddles are 143 exactly where you're placing the bones. Some people need wider to 155, some can use 130.
A soft saddle almost guarantees that the bones will sink in enough to create more perineal pressure than a less forgiving sitbone surface.
But the sitbones do need to adapt to the pressure of your torso's weight, so it takes some weeks of consistent riding to get to that point.
Small changes in the saddle tilt, based on your riding position, will have huge affect on comfort. Some find it easy to adapt to any saddle; others hunt for a long time til they get a good match.
Usually - soft/padded - is very counterproductive to longer times in the saddle.
