I've tested the alphaburly pro in 10 below farenheit and was cold ankles up. They need to insulate the legs with 12mm neoprene. So does muck. The arctic pro is superior to the arctic ice which rip in half in less than a year .I've had mine 7 years. Chainsawing and hauling brush at 25 below I had double socks on and had to use shake hand warmers for my toes. I think muck needs to make a 12 to 18mm neoprene high and medium height Antarctic pro with a safety toe
The age old Thinsulate dilema... Thick neoprene will always trump a thin Thinsulate boot. Thinsulate is awesome in active situations, but struggles in sedatary applications. Your feet produce very little heat if you are not moving, so the thinsulate has nothing to bounce back to the feet. I have 7mm Neoprene (12-18 is crazy thick!) Lacrosse boots and they are one of the warmest boots I have owned. Absolutely love them.
Was a great boot as would last 3 seasons of hunting and walking miles with them, but I have had a few these days and I have returned some as water bubbles coming from seems and only lasting about just over a season so I have not bought them since.
I've worn muck boots for several years. The last three years, muck boots have been junk. I wear muck boots daily. The Arctic Pro and Arctic Icei didnt even last the winter. The muck chore boots were even worse. Didn't last a month. Poor quality and workmanship. Switched to a Sam's Club rubber boot for 69.95. Have lasted over a year. Super warm and comfortable.
