Bunny Boots Rock!!!!
I work in the arctic, of Alaska, 20 years on the north slope, I’ve tried them all, and tested them all to temperatures to 70 below ambient and wind chills as low as 112 below zero. I am an ice fisherman from south east Minnesota, who fishes not only the backwaters of pool 8, but Mille Lacs, LOW, Sylvia Lake, Red, Wisconsin Lakes in the Spooner Wisconsin area. I have tried different boots that the oilfield has provided me over the years, and I am going to share some feedback.
Bunny Boots, the warmest out there, yes they are heavier, but, (even with bare feet) these will never get cold. approx. 50$-100$ Ebay, also available at Army Navy Surplus stores. Easy to dry out, wipe with paper towel, and done.
FYI: The white style Bunny Boot seems to be warmer than the black version known as the Mickey Mouse boot.
Baffins, warm boots, aka Pac-Boot seem to trap moisture from feet, which causes freeze up at extreme cold temperatures, very expensive, i threw mine away, as my feet were aching second day of use, best if worn and not moving, takes a long time to dry with boot dryer. I do not like these, to each there own, just my honest opinion.
Mucks, or Muck style, rubber and neoprene, Great boots, feet get cold at extreme cold temperatures. Not very expensive. Good for ice fishing for sure, lighter than bunny boots, but not as warm as Bunny Boots.
Neos Navigator Stabilicers Overshoe, 120$ “Over Boots” These you can wear right over any boot, or even shoes you have, they offer great warmth, and traction built in. A second favorite for warmth by the majority of workers in the Arctic. Bulky and almost impossible to drive in, but easy enough to put on and off. We put plastic grocery bags over our boots to help slide these on and off. Would be great for ice fishing, however, I have not brought a pair home yet.
There are lots of other choices, like pack boots, Insulated rubber boots, Neoprene rubber boots, etc…
Pack Boots such as Baffin, not good for lots of moving around as sweat builds up in insulation, then gets cold. Rubber Neoprene are great at warmer conditions, just not at extreme cold temps beyond 20 below… My choice would be the Bunny Boot then the NEOS when its colder than 20 below.
The way I see it for the price of a pair of Baffin or pac boots, a person can buy one pair of Bunny boots for extreme cold, and a pair of Muck like boots for everyday ice fishing.
Just wanted to share my opinion on boots, along with the mast majority of over 10,000 employees who work in the oil fields of the north slope of Alaska. Tight Lines!!!!
Now 1 thing I want to add is that if you can come across a size 10 regular or wide let me know at that price. I’ve been all over the internet looking. Ya stuff that is beat up and worn out is out there. Otherwise your looking at a couple hundred bucks for a good pair. PM me with your finds.
