i don't usually review stuff, but i thought this one deserved it.  i have had these about 2 months - they have broken it a bit and have gotten very comfortable to wear.  i am on my feet in them for 6-10 hours - running back and forth on a concrete floor, climbing ladders, walking on machinery and steel chutes, etc.  my feet don't hurt and i don't mind wearing them every day.  they aren't too heavy for steel toe boots either, although they make a nice loud sound if you drop them on the floor so they are nice heavy duty badass boots buy them
