I suspect that by canceling the Martens lifetime warranty they have canceled the world renowned quality. I bought them in October 2021 and now there is a crack in the sole. They may have even lasted less as I only noticed because it was raining and I felt my left boot pinch. I work from home and wear them most of the time when I walk my dog or go shopping. My first pair of papers and they're pretty disappointing. The website says 5 to 20 years, I think my mileage may vary.
