These seem *really* pretty solid, which has been an issue I've had with Hanes in the past. Although I'm a size 10.5 and these should be a 10-13, they are *very* tight and uncomfortable. Also, they don't breathe at all, so they get very hot when hiking and very smelly when I take my shoes off (which wasn't a problem with other sock brands). So I'll look for something else. Too bad I only have 2 packs.
