Update:Last pair lasted from August 2018 until December 2021. 3 years, 4 months.Current pair purchased December 2021 is going strong but could use some new insoles.By far the best boot I have ever put on my feet - in terms of comfort.I have owned 8 pairs of this exact boot over 12 years, and while that seems awfully high please let me explain.First, size.I have been in many an argument with shoe store sales people. I buy these in a 12. Period. They will insist that I then wear a size 12, period.However every other brand of shoe I have ever purchased has been a 13 to 13.5. Take that information as you will though, because those other brands are equally likely to just run large.Are these waterproof?Absolutely not. But I do have a waterproof model of Bates boots which have been flawless, though I only use them a couple times a year.Comfort?Day one, fresh out of the box, I put these on and go to work without a concern in the world.Longevity:Isn't as high as one might expect from a work boot, but its fine for the price with one caveat. My previous job had my boots exposed to various oil and antifreeze products plus inclement weather, road salt, chemicals, and miles of walking per day and these would last me just over a year before the bottom would start to peel loose.My current job however is indoors and while I put more miles on than ever before they are not subject to all the harsh conditions. I spend 9-12 hours a day on my feet on concrete floors and rarely find myself uncomfortable at the end of the day. As a result of staying out of the harsh conditions however the boots last me 2-3 years easily.I also wear them almost exclusively. They are so comfortable that I don't even bother to change out of them when I get off work. That's not something many boots can claim.My current pair was purchased August 2018, so 2.5 years and counting. See photo posted to this review.The caveat:Whether your employer reimburses you on them or not. If you have a harsh environment and no reimbursement, don't buy these. If they do, these might be well worth checking into at least once. If you are working indoors on your feet all day? Expect 2-3 years from them. Possibly more if you only wear them at work.As long as my employer continues to reimburse for work boots I will continue to buy this exact model and size of boot until the day I die or Bates stops selling them.
