I've been climbing in Red Dawgs for for probably 7 years now and I like them just fine. Seem to hold up as well as any boot in our working conditions. I wore the 12" when I was working more ground, then bought the 16" when I started climbing a lot. Eventually the 12" blew out on the side after 3 years of hard use, but I was climbing in them and they're not even reinforced for wearing spurs. The 16" hold up better than that since they're more reinforced. Haven't had a problem with blisters or sore feet.
