I work around quicklime. It will give you a chemical burn in about two hours, depending on how much you get on your skin. Mixes with your sweat, then oxidizes. Feels like sunburn. When mixed at about a 1 part quicklime to 2 parts water, it will heat up to 250 F, and melt it's way through a styrofoam cup.
Even when neutralized, the dust is abrasive. Add the continuous pounding on steel and concrete for twelve hours at a shift, and some foot shtank from the inside, and the combination simply dissolves leather boots. Gore-Tex would help with the sweat, I wear socks that wick pretty good, but traditional leather lasts about eight months if not treated.
I've oiled and waxed my boots. That was washed away by one day of mixing hot dust with water for cleanup. The outsole started separating from the upper a week later, and now I walk around with small pieces of grit in my boots all day.
Direct attached soles seem to last longer than traditional stitched soles, because the dust eats the stitching. Shame, too, since the stuff gets slippery when it gets wet, and some logger soles would be nice. Likewise, some pull-on boots would be nice since they would stay waterproof longer.
So what I'm left with is a pull-on style boot with an aggressive tread pattern, a direct attached sole, Gore-Tex lining, steel toe caps, EH protection would be nice, and some sort of protective coating on the leather.
It would be great if I could get somebody to Rhino-Line a pair of boots.
I wasn't going to list all of the requirements here, but, hey. Why not?
