for what its worth, my danner quarry boots are holding up though I did bust a stitch on the heel somehow recently and the waterproof gortex liner gave out within about a year. think I am on year 2 or 3 with them, think they should hold up until about mid year next year as ive wore the front lip to about the stitches at the front of the toe from kneeling at work.
as for my danner 6" bull run moc toe, I got about a year out of them before the sole started separating, had it resoled locally and that peeled. sent it to danner and had them resole it for a second time and fix the cracked plastic safety toe that was stabbing my foot while walking. got the boots back with new soles and a unrepaired toe cap. ended up with a new pair of bull runs under warranty from danner they arrived with separating soles new out of the box. currently intermittently wearing them but I know im gonna end up tossing them out soon.
as for my winter boots, my three year old red wings Irish setters foreign made.. are holding up much better and I have yet to have a single complaint surprisingly.
have some thorogood boots too, busted heel stitch, soles nearly worn off but holding up good.
