I have some SDs in black roughout with lowered block heels and like they way they look as much as the standard height/shape heel. Comfort-wise I also feel no meaningful difference, although I do feel a very slight extra hump in the arch with the lowered heel, which makes sense (although with a survey of one pair and a very subtle, possibly imagined, difference I cannot say for certain the heel is the cause). I also have a pair of BHs with a standard-height block heel and it really feels no different to the woodsman heel TBH, so I consider the heel choice largely aesthetic at this stage of my White's game. In fact I'm considering a standard-height block heel on my brown bison SD order, which I guess might also be considered a sin, tooI'm considering committing a sin and changing my black semi dress order to lowered block soles. Having tried both I don't really feel a difference in arch support and I think the lowered sole looks better with the unstructured SD.
