This is really Greate Boots! I am Outdoorsmen. My Job is Radio Ralay Station Support. I Worn My Corcorans During Last Seven Years. That Was Really Hard Test for The Pair of Corcoran. I Worn Them from -20F to 90F in Rain, Snow, Sun, Mud and I Had no Problems. Now My Son Wears The Same Pair. And They are Eight Years Old, but in Good Condition! So, Theese Boots is The Exellent Footwear for Life.
