6 Best Pac Boots For Minnesota Ice Fishing That Handle Sub-Zero Temps
We review 6 top pac boots for Minnesota ice fishing. See which offer the best warmth, waterproofing, and traction for sub-zero days out on the ice.
The wind whips across a vast, white expanse of Lake Mille Lacs, rattling the canvas of your ice shelter. It’s ten below zero before the windchill, and the only thing between you and a dangerously cold, miserable day is the gear on your body. Nowhere is that more critical than on your feet, because once your toes go numb, the trip is effectively over. Choosing the right pac boot isn’t just about comfort; it’s about safety and your ability to stay out on the ice when the bite is on.

Key Features of Sub-Zero Ice Fishing Boots
When you’re standing on a foot of frozen water for hours, your boots are your personal furnace. The three non-negotiables are insulation, waterproofing, and traction. Insulation is often measured in grams (like Thinsulate) or described by the thickness and material of a removable liner (like wool felt or proprietary multi-layer synthetics). Don’t get too caught up in the manufacturer’s temperature rating—think of it as a guideline, not a guarantee, as your personal circulation, activity level, and sock choice play a huge role.
A true pac boot features a 100% waterproof rubber lower shell that extends up over the ankle. This is critical for drilling holes, landing fish, or navigating the inevitable slushy spots. The upper part of the boot is typically a durable, water-resistant material like leather or nylon that handles deep snow.
Finally, look at the outsole. Deep, aggressive lugs are great for trekking through unpacked snow to your spot. However, some rubber compounds are specifically designed to stay softer and grippier in extreme cold, providing better traction on slick, windswept ice. There’s a balance here; the most aggressive tread isn’t always the best for the flat, hard surface you’ll be on all day.
Baffin Impact: The Ultimate Sub-Zero Protector
Stay warm and secure in extreme conditions with Baffin Impact Snow Boots. Featuring a locking snow collar, double buckle fastening, and a multi-layer inner boot system rated to -148 degrees, these boots deliver superior insulation and comfort.
If your ice fishing style involves finding a spot, setting up a shelter, and staying put for hours in the most brutal Minnesota cold, the Baffin Impact is your fortress. These boots are built with one primary goal: maximum warmth in stationary situations. They boast an extreme temperature rating, achieved through a unique multi-layer inner boot system that wicks moisture, insulates, and reflects body heat.
The tradeoff for this incredible warmth is size and weight. These are large, somewhat cumbersome boots that feel more like moon boots than hiking boots. They aren’t designed for long, active treks across the lake. But for the angler who prioritizes warmth above all else while sitting on a bucket in a sub-zero wind, the Baffin Impact is arguably the warmest consumer boot on the planet.
Sorel Glacier XT for Extreme Cold and Comfort
For those who want extreme cold protection from a brand that has defined winter footwear for generations, the Sorel Glacier XT is a legendary choice. It’s a classic pac boot design, modernized for serious performance. This boot is built around a thick, removable 13mm ThermoPlus felt inner boot, which is augmented by an Omni-Heat reflective lining to radiate your body heat right back at your foot.
The Glacier XT features a handcrafted, waterproof vulcanized rubber shell that is famously durable, paired with a water and wind-resistant upper. While still a heavy-duty boot, it offers a more traditional fit and feel than some of its extreme-cold competitors. It’s a proven workhorse that provides an excellent blend of warmth, durability, and all-day comfort for long days on the ice.
Kamik Greenbay 4: A Lightweight, Flexible Option
What if you’re an active angler, constantly on the move, drilling holes, and checking tip-ups? The Kamik Greenbay 4 is built for you. Its primary advantage is its remarkably light weight and flexibility compared to other boots in its warmth class. This makes a huge difference in fatigue at the end of a long day of walking through snow.
The warmth comes from an 8mm Zylex removable liner, which does an excellent job of wicking moisture and retaining heat, especially when you’re generating some of your own. The waterproof rubber lower and adjustable nylon upper keep the snow and slush out. While its -40°F rating isn’t as extreme as others, it’s more than enough for most Minnesota days, especially if you’re not sitting perfectly still for eight hours straight. It represents a fantastic balance of mobility and warmth at a very accessible price point.
Muck Boot Arctic Pro for Guaranteed Waterproof Warmth
Sometimes the biggest challenge isn’t just the cold, but the wet. For those early or late-season days with slush, overflow, or deep, wet snow, the Muck Boot Arctic Pro is a game-changer. Its defining feature is a tall, flexible neoprene upper that makes the entire boot 100% waterproof from sole to cuff. You can step into deep slush with total confidence.
The slip-on design is incredibly convenient for getting in and out of the truck or ice shelter. The fleece lining and thermal foam underlay provide significant warmth, making it a true sub-zero contender. The main tradeoff is the fit; without laces, it doesn’t offer the same locked-in, ankle-supporting feel of a traditional pac boot. For anglers who value absolute waterproofness and convenience, however, the Arctic Pro is tough to beat.
LaCrosse Ice King: Durability for a Lifetime
In a world of synthetic materials, the LaCrosse Ice King stands as a testament to old-school, bombproof construction. This is the boot you buy once and potentially hand down to the next generation. It combines a heavy-duty, waterproof rubber bottom with a full-grain, oil-tanned leather upper that is tough, water-resistant, and can be treated for years of service.
Inside, a thick, removable wool felt liner provides breathable, reliable warmth that has been trusted for decades. This boot is heavy, and the leather requires a break-in period, but the payoff is unparalleled durability and a custom-like fit over time. For the angler who sees their gear as a long-term investment and values heritage quality, the Ice King remains a top-tier choice for fighting off the cold.
Cabela’s Inferno Pac Boot: Warmth on a Budget
Serious warmth doesn’t always have to come with a premium price tag. Cabela’s Inferno Pac Boots are designed to deliver an incredible amount of insulation for the money, making them a fantastic option for the weekend angler or someone just getting into the sport. They are often packed with 2,000 grams of Thinsulate Ultra Insulation, a massive amount that competes with boots costing nearly twice as much.
To hit this value, the materials may not have the same premium feel or long-haul durability of a LaCrosse or Sorel, but the core function—keeping your feet warm in sub-zero temperatures—is absolutely there. They feature a standard waterproof rubber shell and a durable nylon upper, providing all the essential features needed for a comfortable day on the ice without breaking the bank.
Choosing the Right Size and Fit for Pac Boots
Getting the sizing right on pac boots is the single most important factor for warm feet, and it’s different than fitting a sneaker or hiking boot. Your goal is to have enough room for your thickest wool or synthetic socks plus extra space for air to circulate. That trapped air is a critical layer of insulation.
When trying on boots, do it at the end of the day with the exact socks you’ll wear fishing. You should be able to wiggle your toes freely. If your toes are pressed against the end or the sides of the boot, it’s too small. Tight boots restrict blood flow, which is the fastest way to get dangerously cold feet, no matter how much insulation the boot has. Always err on the side of a little too big rather than a little too small. You can always add a thicker sock or an extra insole, but you can’t fix a boot that’s too tight.
The best boot isn’t the one with the most extreme temperature rating; it’s the one that matches your activity level, your budget, and your tolerance for the cold. Whether you need a mobile and lightweight option for hole-hopping or a thermal fortress for sitting still, the right footwear is out there. Don’t let the fear of cold feet keep you inside—gear up wisely, get on the ice, and enjoy the unique peace of a Minnesota winter.
