I trash my boots. I work with high performance concrete. Not driveways and slabs, but furniture, sinks, counters, sculpture, etc. I meant to keep these nice looking boots for site visits and installs, but they were so comfortable that I ended up wearing them all the time. They have repeatedly gotten slopped all over with concrete, acid, sealers, and so on. Concrete is very abrasive and the high alkalinity burns much like an acid. All this abuse did finally split the seam on the front top of my right boot where the toe box bends. The liner is still intact and my foot has not gotten wet. I may just epoxy the seam. Considering what I've put these boots through in the last 19-20 months I'm going to call this a win and I'll be buying another pair. Other than the split seam and the caked on concrete these boots are still fine. Also, most boots have inadequate inserts and I would end up buying better ones for about $40 a pair. These boots come with top of the line inserts, so consider that in the cost too. So far, these have been my favorite work boots ever.
