These are not built for the common construction site.  Forget about steel toes and stuff like that.  I'm in the swimming pool industry, so I'm not talking about commercial sites where OSHA controls what you where.  The tread on the bottom of the boots has such wide gapping that small crushed stone gets stuck in it very easily.  It's not just annoying, but it could damage wood decks or nice natural stone decks if you walk on them with a stone or two stuck to your boot.  The leather is also noticeably weaker than other Lugz I've purchased in the past.  It's a good-looking, comfortable boot, but not good for working construction.
