I have the made in USA Double-H harness boot and they have the Sierra 150 Orange Plaug outsole. Very comfortable and the soles have a great grip on pavement.
I also ride with the Red Wing boots. I have a pair of black 6" 607s that took no breaking in at all. They come in widths out to "H" which is really wide. Also because they are not a molded sole, they can be resoled.
I have a pair of these RW 986's I purchased brand new in 2012, worn once for about 5 minutes, a little too tight, never took them back if anyone would like to purchase?, still like brand new, without box ... $125 shipped
