Danner has some boots that are similar. Look at this thread: http://www.styleforum.net/t/270451/danner-stumptown-collection
You can check their website also. Don't know if it matters but not all of their boots are made in the USA. You have to check individual items to see.
Also, if you search "wedge sole D ring hiking boots", you'll get a lot of results similar to these photos.
