Danner, LaCrosse, and Irish Setter. I own a pair from all three and have not had a single problem with any of them. I have had Rocky's in the past and they didn't seem to hold up as well as these do.
I also, IMHO, found that Rocky's seem to be a bit heavier than the others. This was a few years ago since i checked so that may have changes with the new technologies that everyone is using.
