Ok so as good as a danner? No I don't think so mine ripped where the nylon meets the leather at the laces I'm not happy about my only pair of duty boots dropping out. I had to send them back to Bates at my expense and have to wait another 2 weeks till I either get them or one of another pair I had to pick. That being said if worse comes to worse at least ill get my money back ( I'm currently forced to use a pair of doc martins that are not duty boots no ankle support) the boots I'm using now are comfortable but no ankle support is killing me. If I get another pair of the same back and they rip then ill switch to a 5-11 or possibly a doc martins industrial. They did take them back but I'm not happy. Right now I'm using whatever black boots I have left (3 pairs one is so worn out the leather is full of holes one is definatly not a duty boot and the last is too low) I don't think its too much to ask for to have a boot hold up till I get them back I cant recommend these and if they tear again then I am done with Bates. I hope this was a manufacturing defect. Whatever happened to 1000 denier nylon or codura nylon. 1680 seems to be cheaper but in this case cheaper is worse.

Additional information
Bates took back my damaged pair and admitted they made an error then they replaced my boots free of charge. they seem to be a new issue pair that look to be superior to what I had I just broke them in and they are definately comfortable as I said before better still it only took 2 weeks total I was expecting 3. The new issue 3135 looks the same but the nylon seems to be thicker so I conclude by saying bravo Bates for standing behind your product and thank you for making it right
