I wore these boots nearly continuously  for a year or so.  (I usually only have 1 pair of shoes/boots I wear at a time)  I wear a size 15, with some custom arch supports and am not a "light weight" so I'm very hard on shoes.  These held up better than I expected.  WIth cheaper brands like Hi-Tec, Columbia etc I got about 6 months out of them.  Since I have a funny wear pattern I rub the heels and balls of my feet hard and once they're gone, the shoe is useless to me.  It's at that point now.  The sole is separating in a couple of places but the hardware has held up wonderfully.  I liked them so much I just ordered my second set!
