They have a place for me- I wear gray pants a lot, and it's nice to have a black casual shoe. I know this board likes brown with gray, and I often wear that myself, but black really does work better with gray in most contexts, IMO. So I wear black loafers
In a 5 shoe wardrobe, I don't think I'd recommend them, I'd just wear something like black longwings instead, which doubles as a suit appropriate shoe.
That seems sensible. I wear grey pants a lot too, but usually brown feels like the right choice. Perhaps it's just the rest of my wardrobe and/or habit at this point. It's pretty difficult to argue with black longwings as a second black shoe if there is to be one in a 5 shoe wardrobe; that seems like a solid choice.
