I've found mesh fabrics to last longer. I haven't tried a good quality leather boot. It's usually out of my price range. More importantly than durability from damage and protection from the elements, I need flexibility and leather can only provide that if it's very high quality leather, properly stitched, and proper leather care. I simply do not have the money nor do I want to put in the effort for all of that. I've tried a low quality mesh product that costed $70 and it lasted twice as long as my Redwing boots that cost $200 on a huge clearance. I know redwing isn't very reputable anymore but my point is that mesh lasts longer for me because I need the flexibility in my field as an automotive technician constantly bending down and walking.
