Right kind of boots for the Job

I work at a large Gold mine in Alaska, and we are on our feet 12 hours a day.  I am a fueler/mechanic and climb up and down equipment daily.  Sometimes like 40 times a day.

So foot wear is important, so this newest pair of boots are from Danner, Quarry  style.  See photo 

These boots are warm, comfortable and you hardly notice them when wearing them.
