Update:this is my 4th consecutive pair , genially they are lasting between 12-18mths before seams start getting loose or the soles start tearing through.
Previous:While they are on the heavy side of work boots they are much lighter than my old Carolina and Georgia met guards were, after all protection is the key thus they are going to be a bit heavy. They are very comfortable, probably the most comfortable saftey boot I've ever worn/owned. Stitching is great and has held up well throughout the boot. The only bad thing I have against these boots is the sole tore just under the ball of my foot causing the welt stiching to rip out as well. That said I weld daily in a tank manufacturing setting as a Welding/Fab. Supervisor so I'm constantly squatting or bending into awkward positions. They are great to walk in as well. I'm pretty critical of things like this, mine are worn out with stitching torn from soles about 1/4 the way around the inside of each foot. Left sole is crack all the way through, all the way across which happened at about 9 mths of wear and I'm currently at about 13 mths. There is a hole from accidentally having my foot on a grounding stud while welding seated. Soles melt quickly. I also took them to a boot repair place as soon as I got them to have brass eyelets put in the lower holes as it's just punched leather, although it's doubled. Didn't want to take the chance, well worth the extra $12. Thinking of buying another pair as DM says that they can't be resoled. I came out about 4 mths sort of my goal to replace these and about 6-8 mths sort of what I thought lifespan would be.

Pros: comfort while standing or walking, safe, well made, respectively cheap

Cons: soles too soft for continuous squatting, not re-solable,
