I've had a pair of Muck boots for the past couple years and they finally wore out enough that I bought a new pair but this time I bought Bog boots to see if thy were better. The Muck boots were great and my feet were always kept warm and dry no matter what I was doing. But these Bog boots I bought for this year were great too they kept my feet surprisingly warm during -10 degree weather during an all day sit for Ohio's muzzle loader season. The Bog boots are rated for -40 degree weather. I think both Muck and Bog boots are great for deer hunting but I think Bog boots are slightly better and I got them for $98 compared to Muck boots which are $120.
