I work outside in mud, rain, concrete, gravel..etc and after 6 months they still look just like the day I bought them minus some scuffs on the front protective toe which is very uncommon with most every other brand I have tried before including Redwings. I can usually wear out a boot, at least to the point where they no longer are fully submersible underwater within 6 months. These are still fully submersible and I can stand in water indefinitely up to about 8 inches deep.The only con was the break in time. Their very stiff and theres a couple places in particular that hurt me for a couple of weeks or longer before it conformed to my feet. Since these are high heeled, if you get tacky mud stuck on the bottom, you have to scrape it off on a rock or something before you can walk. The kevlar stitches do still wear down like any other but have not come apart.It's definitely a rock solid and durable boot even though they aren't the prettiest.
