Under Armour Men's Brow Tine 400 Insulated Boots Realtree Camo/Brown (8.5M)

These have been the best boots I've ever had for hunting, Wore them at -46 pushing bush in waist deep snow, my feet stayed warm and comfortable. I've also wore them bow hunting at -23 where I broke through the ice over the slough I was hiding in, feet went into the water/ mud about ankle deep; the boots kept my feet warm and dry. These are the best boots I've owned, will definitely be buying another set when these ones kick the bucket. Thanks Under Armour

As a contractor and work all over the northern states I run in to all kinds of cold weather conditions. Recently I was on a project in wyo. and the temps dipped to near zero. I was freezing my feet in the boots I took with me. I found these on line and ordered them for next day delivery. When I got them the first day was - 4 my feet never got cold nice and cozy. I did by them a half size bigger and they fit perfect. I wore the with one pair of heavy socks and I swear I never got cold. My wife also bought a pair of women's her size and we had to send them back to small by a half size so I recommend a half size bigger than your street shoe size. Very light boot no break in required
