My husband works in construction and these are the only boots he wears!  He was amazed with his first pair at how comfortable they were...and they last as long as any pair he has owned.  They are steel toed but not heavy feeling and the 6" ankle is supportive but not restrictive. My husband works many 80 hour weeks on his feet the whole time, in all sorts of weather and he swears by these.  He says once you've worn Rockies, nothing else will do! The comfort is their main claim to glory!
